2INTRODUCING THE Vi-CELL XR 2
2.1
SYSTEM OVERVIEW
The Vi-CELL XR Cell Viability Analyzer is a video imaging system for analyzing yeast, insect
and mammalian cells in culture media or in suspension. It automates the widely accepted
trypan blue dye exclusion protocol and is designed to analyze a wide variety of cell types. The
software includes features to monitor bioreactors and other cell culture processes and is
designed to comply with the US Food and Drug Administration’s (FDA) regulations on
electronic records and electronic signatures (21 CFR Part 11).
The main features of the system are:
2.2
r
Cell Viability reported in percentage, concentration and cell count
r
Concentration range of 50,000 to 10,000,000 cells per mL
r
Cell size range of 2 µm to 70 µm
r
12-position auto-sampler
r
User-friendly reagent system
MEASURING VIABILITY AND CELLULAR PARAMETERS
Why Measure Viability?
The measurement of overall health of cell cultures requires accurate measurements of both
cell concentration and percentage of viable or live cells. This data is essential to the decision
making process for basic tissue culture cell growth and maintaining optimum culture
conditions in bioreactors.
Historical Perspective – The Hemacytometer
Cell viability (Trypan Blue Dye Exclusion Method) determinations traditionally have been
performed using a light microscope and hemacytometer. Unfortunately, this technique has
numerous major shortcomings. The hemacytometer has a significant repeatability error.
Different technicians analyzing the same cell sample obtain variations in results. In addition,
the manual method is tedious and quite time consuming for today’s busy laboratory
environment.
2.3
HOW VIABILITY IS DETERMINED
The Trypan Blue Dye Exclusion Method
The widely accepted method for cell viability determination is the Trypan Blue Dye Exclusion
Method. When cells die, their membranes become permeable allowing for the uptake of the
trypan blue dye. As a result, the dead or non-viable cells become darker than the viable cells.
This contrast is what is measured in order to determine viability.
An Image Analysis Solution
The Beckman Coulter Vi-CELL XR automates the Trypan Blue Dye Exclusion Method.
Utilizing the latest in video capture technology and sample handling, the Vi-CELL XR takes
the cell sample and delivers it to a flow cell and camera for imaging. The Vi-CELL XR will
then capture up to 100 images for its determination of cellular viability.
PN 383674B
2-1
INTRODUCING THE Vi-CELL XR
HOW VIABILITY IS DETERMINED
The software determines which cells have absorbed trypan blue dye and those that have not.
Cells absorbing the trypan blue dye appear darker hence have lower gray scale values. Cells
with higher gray scale values are considered viable.

CREATING AND MANAGING CELL TYPES
What Is A Cell Type?
Cell types are files that store the optical settings required to correctly identify and quantify
viable versus non-viable cells. Cells will vary in their optical characteristics and
understanding how to establish the correct settings will be important.
For many cell types, the default cell type values are suitable. In the event any of the
parameters must be changed for a given sample, a new cell type may be created or an existing
one modified. This section is an attempt to help you better understand how to setup the
Vi-CELL XR for a given cell type.

Under the General tab, enter the appropriate information for your cell type, the minimum
and maximum cell diameter, the number of images (max. 100) to acquire for the
particular cell type and dilution factor if necessary. Use the default settings as a starting
point if necessary. Use the minimum diameter parameter for excluding cellular debris or
unwanted cells. Use the trypan blue mixing cycle to adjust for cell lines that tend to
shear under the stress of mixing. For insect cell lines, a mixing cycle of 1 is found to be
suitable.

Under Image Analysis set the parameters accordingly. Utilize the default settings as a
starting point.
The first four parameters control the image recognition portion of the Vi-CELL XR
software. The first two control cell recognition whether viable or not, and the second set
of parameters control whether a cell is viable or non-viable.
The minimum circularity parameter is for eliminating debris such as dead cell fragments.
This parameter only works on dead cells or debris. The range is 0 to 1, with 1
representing a perfect circle. If you find viability results a bit low, and there is debris,
begin with a setting of about 0.7 and adjust accordingly.
Note: For steps 3 and 4, perform an initial analysis to get an approximation as to cell size.

Modify Cell Type
Minimum Diameter: The minimum diameter of the cell type. 2 is the minimum diameter
allowed. The minimum diameter can be used to exclude debris and/or unwanted cells.
Maximum Diameter: The maximum diameter of the cell type. 70 is the maximum diameter
allowed.
Images: The minimum or maximum number of images to capture for a given Cell type. 100
images is the maximum allowed.
Aspirate Cycles: In order to ensure that all of the cells are equally dispersed some of the sample
is aspirated and then returned to the cup. One cycle is normally sufficient but if the cells are
difficult to keep in suspension and have a tendency to attach themselves to the walls of the
cup then additional aspirate cycles may be beneficial. The range of values for this parameter is
0 to 9.
Trypan Blue Mixing Cycles: The trypan blue and sample are mixed by sending the mixture back
and forth between the cup and syringe. This parameter determines the number of times that
the mixture is returned to the cup. Normally three times is sufficient but if the sample is
immiscible with trypan blue then a higher value may be necessary to achieve good mixing
and even background intensities. The range of values allowable is 1 to 9.
This feature is especially useful for cell types, which may shear due to excessive mixing.

SPECIAL SOFTWARE FEATURES
CREATING AND MANAGING CELL TYPES
Lowering the number of mixing cycles will alleviate this situation. For insect cell lines, it has
been determined that 1 mixing cycle is most suitable.
IMPORTANT When modifying or deleting a cell type, the current active cell type is selected. Verify this is
the cell type for modification or deletion.
Cell Brightness: Is the brightness of the cell boundary within a given image. The range is 50%
(darkest) to 90% (lightest). Different cell types will have varying cell ‘brightness’ settings. The
software detects the transition from dark (cell boundary pixels) to light (background of the
image). A lower value means a dark boundary will be required for cell identification. A higher
value means a lighter boundary.
Cell Sharpness: Represents the “clarity” of an image. Enter a range from 1 to 200. 1 represents
sharpest, 200 unclear. This value also affects the transition from cell boundary (dark) to light
(background).
Viable Cell Spot Brightness: Is the brightness of the center spot of the cell. The range for spot
brightness is 0 to 100%. 75% is a typical value.
Viable Cell Spot Area: The cell spot area will be a percentage of the total area of the Cell. 5 to
10% are typical values. Any extremes in this value will either make the cells all viable or
non-viable.

SPECIAL SOFTWARE FEATURES
CREATING AND MANAGING CELL TYPES
Minimum Circularity: (Least Circular=0, Perfectly Circular=1) A non-viable cell will only be
accepted if its circularity is greater than or equal to the minimum circularity. This parameter
can be used to reject debris that exceeds the minimum cell diameter and are too irregularly
shaped to be treated as a real cell. This parameter only affects dead cells.
Decluster Degree: The amount of ‘de-cluster’ applied to the sample. The selections are none,
low, medium and high de-cluster. The default setting is medium. This function increases the
ability of the software to detect cells that are clumped together. Set the de-cluster degree
according to how well the cell clusters appear within the images (if not de-clustered
properly).
Note: The cell brightness and sharpness help determine whether or not the boundary “dark”
pixels belong to a cell or are part of the background. The cell spot brightness and area
determine whether or not a cell is viable or non-viable.

8REGULATORY COMPLIANCE – 21 CFR PART 11 8
8.1
21 CFR PART 11
The Electronic Records and Electronic Signatures Rule (21 CFR Part 11) was established by
the FDA to define the requirements for submitting documentation in electronic form and the
criteria for approved electronic signatures. This rule, which has been in effect since August
20, 1997, does not stand in isolation; it defines the standards by which an organization can
use electronic records to meet its record-keeping requirements. Organizations that choose to
use electronic records must comply with 21 CFR Part 11. It is intended to improve an
organization’s quality control while preserving the FDA’s charter to protect the public. Since
analytical instrument systems such as the Vi-CELL XR Cell Viability Analyzer, generate
electronic records, these systems must comply with the Electronic Records Rule.
Here are described the relevant portions of the 21 CFR Part 11 regulations and their
implementation using the Vi-CELL XR control software explained. It is important to realize
that implementation and compliance of the rule remains the responsibility of the organization
or entity creating and signing the electronic records in question. Proper procedures and
practices, such as GLP and GMP, are as much part of overall compliance with these
regulations as are the features of the Vi-CELL XR control software.
8.2
ELECTRONIC RECORDS
Section 11.3 subpart A of 21 CFR Part 11 deals with the definitions assigned to electronic
records, ‘electronic record means any combination of text, graphics, data, audio, pictorial, or
other information representation in digital form that is created, modified, maintained,
archived, retrieved or distributed by a computer system’. In reality this refers to any digital
computer file submitted to the agency, or any information not submitted but which is
necessary to be maintained. Public docket No. 92S-0251 of the Federal Register (Vol. 62, No.
54) identifies the types of documents acceptable for submission in electronic form and where
such submissions may be made.
8.3
FDA REQUIREMENTS
In the general comments section of the ruling the following is stated: ‘The agency emphasizes
that these regulations do not require, but rather permit, the use of electronic records and
signatures’. In the introduction to the final ruling the following statement is made ‘The use of
electronic records as well as their submissions to FDA is voluntary’.
If electronic submissions are made, Section 11.2 subpart A comes into play: ‘persons may use
electronic records in lieu of paper records or electronic signatures in lieu of traditional
signatures provided that: (1) The requirements of this part are met; and (2) The document or
parts of a document to be submitted have been identified in public docket No. 92S-0251’.
The Vi-CELL XR control software has been designed to allow users to comply with the
electronic records and signatures rule. Any organization deciding to employ electronic
signatures must declare to the FDA their intention to do so.

IMPLEMENTING ELECTRONIC RECORDS AND SIGNATURES
8.4
IMPLEMENTING ELECTRONIC RECORDS AND SIGNATURES
Section 11.3 Subpart A describes two classes of systems: “closed systems” and “open
systems”. A closed system is one "in which system access is controlled by persons who are
responsible for the content of electronic records". In other words, the people and organization
responsible for creating and maintaining the information on the system are also responsible
for operating and administering the system. In contrast, an open system is one "in which
system access is not controlled by persons who are responsible for the content of electronic
records".
A typical Vi-CELL XR installation will need to have a procedure designed to ensure proper
operation, maintenance and administration for system security and data integrity. Anyone
who interacts with the system, from administrators to users, must abide by these procedures.
Therefore the ultimate responsibility is with the organization generating electronic records
and signatures. The Vi-CELL XR software is a component, albeit a vital one, of the overall
process.
8.5
CONTROLS FOR ELECTRONIC RECORDS
Subpart B, Section 11.10 describes the controls to be applied to a "closed system". Section
11.30 describes the controls for an "open system", which include "those identified in Section
11.10, as appropriate, and additional measures such as document encryption and use of
appropriate digital signature standards". Since a typical Vi-CELL XR system can be regarded
as a closed system, additional controls for open systems will not be discussed in this
document. The primary thrust of these controls is "to ensure the authenticity, integrity, and,
when appropriate, the confidentiality of electronic records, and to ensure that the signer
cannot readily repudiate the signed record as not genuine". In other words, to protect the data
and to make it difficult for someone to say that this is not their "signature". Many of the
controls described in Section 11.10 refer to written procedures (SOPs) required of an
organization by the agency, for the purpose of data storage and retrieval, access control,
training, accountability, documentation, record keeping, and change control. The other
controls are addressed either by the Vi-CELL XR software itself, or in combination with
end-user procedures.
Of the other controls, perhaps the foremost is described in Section 11.10 Paragraph (a):
"Validation of systems to ensure accuracy, reliability, consistent intended performance, and
the ability to discern invalid or altered records." It is the complete and overall validation of
the system, as developed by the organization, which ensures the integrity of the system and
the data within. It is to this end that the features of the Vi-CELL XR software comply with the
specifications of these regulations.

ESTABLISHING AN ELECTRONIC RECORD
The Vi-CELL XR software employs a system of usernames and passwords, consistent with the
specifications of Subpart C, Section 11.300, "to ensure that only authorized individuals can
use the system, electronically sign a record, access the operation or computer system input or
output device, alter a record, or perform the operation at hand".

If you select the security option (Security, Turn Security On) a dialog box appears requiring you
to enter a user name and password and set the time in minutes for instrument timeout.
Once signed on, click on Security, Add New User to define users and access levels. The Add New
User dialog appears.

ESTABLISHING AN ELECTRONIC RECORD
Figure 8.2 The Add New User dialog screen
New users can only be created and passwords reset by users with Administrator rights. This
file is protected with a checksum and for each user name, contains information on when the
user was created, by whom, at what level, the user’s password in encrypted form and the user’s
file paths. If this file does not exist or if the checksum is missing or invalid then access to the
system will only be possible to a limited number of special users.
File History
The Vi-CELL XR software also performs data input and "operational checks", as specified in
Subpart B, Section 11.10, "to determine, as appropriate, the validity of the source of data
input or operational instruction", and "to enforce permitted sequencing of steps and events".
These two features ensure that, as much as possible, valid data are being entered into the
system, and all required steps have been completed to perform the task at hand.
The purpose of all such data checking and validation is described in Section 11.10, Paragraph
(b): "The ability to generate accurate and complete copies of records in both human readable
and electronic form suitable for inspection, review, and copying by the agency". Vi-CELL XR
software data files are all automatically saved upon creation and protected with a checksum.
Vi-CELL XR software also allows for the capability for backing up data to mirror directories.
Section 11.10, paragraph (e) requires “use of secure computer-generated, time-stamped audit
trails to independently record the date and time of operator entries and actions that create,
modify, or delete electronic records. Such audit trail documentation shall be retained for a
period at least as long that required to for the subject electronic records and shall be available
for agency review and copying.” The Vi-CELL XR software complies with this rule by
8-4
PN 383674B
REGULATORY COMPLIANCE – 21 CFR PART 11
ESTABLISHING AN ELECTRONIC RECORD
generating an audit trail which records the time a user was logged on. The audit trail also will
record and time-stamp: failed login attempts, switching users, turning security on or off,
adding new user, enable/disable user, change password, reset password, and failed checksums.
Electronic Signature
In Subpart A, Section 11.3, an electronic signature is defined as "a computer data compilation
of any symbol or series of symbols executed, adopted, or authorized by an individual to be
the legally binding equivalent of the individual’s handwritten signature". Subpart C, Section
11.100 of the regulation defines the general requirements of such a manifestation. Paragraph
(a) states that "each electronic signature shall be unique to one individual and shall not be
reused by, or reassigned to, anyone else". These two paragraphs, taken together, mean that an
electronic signature is some computer representation of a user's identity, developed to ensure
the distinct and unique identity of that user. The procedural aspect of Section 11.100 requires
that before any such electronic representation is applied, the organization first must "verify"
the identity of that individual. The subsequent use of electronic signatures as the "legally
binding equivalent of traditional handwritten signatures" then must be "certified" to the
agency in writing.
Subpart C, Section 11.200, refers to biometric and non-biometric forms of electronic
signature. Biometric signatures are defined in Subpart A, Section 11.3 as a "a method of
verifying an individual’s identity based on measurement of the individual’s physical feature(s)
or repeatable action(s) where those features and/or actions are both unique to that individual
and measurable". Biometrics are generally regarded as techniques such as fingerprints or
retinal scans, which are considered to be totally unique to each individual and require specific
forms of scanning devices to read and interpret. Non-biometric signatures are those that are
computer generated and, as per Section 11.200, "Employ at least two distinct identification
components such as an identification code and password". It is this form of electronic
signature that is supported by the Vi-CELL XR software.
Generating Electronic Signatures
The Vi-CELL XR software employs User IDs and passwords to verify the identification of each
user logging into the system. When using this technique, Subpart C, Section 11.300 of the
regulation requires "maintaining the uniqueness of each combined identification code and
password, such that no two individuals have the same combination of identification code and
password". This section also requires that the "identification code and password issuance’s are
periodically checked, recalled, or revised". Vi-CELL XR software supports both of these
provisions.
The administration of the system requires that individuals are added to the list of valid
Vi-CELL XR users via the Add a New User dialog screen. The "identification code" or username
of each Vi-CELL XR user must be unique. No two users on the same Vi-CELL XR system can
have the same user name. It is also required that these users supply a password to access the
Vi-CELL XR software, thus satisfying the requirement to "employ at least two distinct
identification components such as an identification code and password". Passwords can be
controlled to prohibit the use of duplicates and to force the selection of new passwords after a
prescribed period of time.
By the implementation of these features, the Vi-CELL XR software can satisfy the requirement
that "identification code and password issuance’s are periodically checked, recalled, or
revised".

ESTABLISHING AN ELECTRONIC RECORD
Applying Electronic Signatures
Subpart C, Section 11.200 stipulates several requirements for the control of electronic
signatures. Procedurally, the regulations require that electronic signatures "be used only by
their genuine owners" and that they "be administered and executed to ensure that attempted
use of an individual’s electronic signature by anyone other than its genuine owner requires
collaboration of two or more individuals". Through the application of Vi-CELL XR user and
password configuration procedures, the system can be configured to "ensure" that
inappropriate use of these identifiers can be performed only by the intentional divulgence of
security information.
Section 11.200 further specifies the use of electronic signature components during a period
"when an individual executes a series of signings during a single, continuous period of
controlled system access", and "when an individual executes one or more signings not
performed during a single, continuous period of controlled system access". This section of
the document represents the "heart" of electronic signature application. To comply with these
provisions, the Vi-CELL XR software uses the application of the username and password to
authenticate the user making and saving the changes, in conjunction with file history and
audit trailing, "to independently record the date and time of operator entries and actions that
create, modify, or delete electronic records”.

EMAINTAINING THE Vi-CELL XR E
The Vi-CELL XR performs the following procedure via the on-board wizard.
Should the system require decontamination, perform the following procedure.
WARNING All instrument decontamination must be conducted under universal precautions for blood-borne
pathogens. Instrument effluents should be regarded as a biohazard. Special care is required when opening
pressurized fluid lines. Appropriate safety equipment must be worn (eye protection, latex gloves, and lab
coat).
1.
Purge the system for 15 minutes with a solution of 0.5% sodium hypochlorite (10%
bleach, prepared by mixing 1 part household bleach with 9 parts water).
2.
Flush the system with water for at least 5 minutes to completely wash the Bleach from
the system. Purge rinse water from the system. Ensure system is thoroughly drained.
3.
Decontaminate the external aspects of the system by washing with 0.5% Sodium
hypochlorite solution (10% bleach, prepared as in step 1 above).
Remove all dried blood or cell culture media from the instrument surface before
disinfection. To remove these substances and prevent scattering potentially biohazardous
material, the blood or culture media should be wetted and softened with the 0.5%
sodium hypochlorite solution. After removal of the dried substances, decontaminate the
surface of the Vi-CELL XR with the bleach solution again. If complete removal is not
possible, expose the instrument surface to the 10% bleach solution for 20-30 minutes.
Rinse the surface with water to remove the bleach.
In the Vi-CELL XR software, there is a Decontamination wizard, which “walks” the
operator through this standard procedure (for the internal components). Select
Instrument and, from the dropdown box, Decontaminate.
