Storage
All buffers and kit components of the InviMag® Plant DNA Mini Kit/ KF96, except dissolved
Proteinase K and SNAP Solution, should be stored at room temperature and are stable for at
least 12 months at these conditions.
Proteinase K: Dissolved Proteinase K must be stored at -20°C. We recommended preparing
aliquots in order to avoid multiple freezing and thawing cycles because this can lead to
decreased enzymatic activity.
SNAP Solution: The magnetic particles should be stored at 2-8°C.
Wash Buffer I, Wash Buffer II, Binding Buffer A: Buffers charged with either ethanol or
isopropanol should be stored at room temperature and must be sealed accordingly. If any
precipitates are visible within the provided solutions solve them by carefully warming up to 30°C.
Room temperature (RT) is defined as range from 15-30°C.

The InviMag® Plant DNA Mini Kit/ KF96 is designed for a semi-automated preparation of
genomic DNA from up to 100 mg of plant material using magnetic beads and the KF96 or
KFflex96 workstation. The isolation process is based on the patented InviMag® technology.
The DNA isolation process relies on the interaction of nucleic acids with coated magnetic
particles at adapted buffer conditions. The KF96 / KFflex96 instrument performs all
purification steps of the DNA purification procedure automatically, except the plant sample
preparation, lysis and initial loading of the system. Sample cross-contamination and reagent
cross-over is effectively eliminated by the provided assay file.
The KingFisher® instrument uses magnetic rods to transport the DNA bound to magnetic
particles through the various assay phases like binding, washing, drying and elution. The
volume of buffers and other liquids required for DNA isolation is reduced to a minimum.
To achieve optimal lysis conditions and high yields, the plant samples are first mechanically
disrupted followed by a lysis step in an optimized buffer system at elevated temperature.
After lysis, a binding step is performed in which the DNA is bound to the magnetic particles
followed by several washing steps before the pure DNA is finally eluted.
The purified and high quality DNA can be stored at -20°C for subsequent use and is readyto-use for subsequent downstream applications like:

InviMag Plant DNA Mini Kit/ KF96 0515
Sampling and storage of starting material
Harvested plant samples can be stored at room temperature for up to 2–3 hours. For shortterm storage (up to one week) samples may be stored at 2-8°C. For long-term storage, we
recommend freezing samples at -20°C or -80°C. Multiple thawing and freezing cycles before
isolating the DNA should be avoided because this can lead to degraded DNA and reduced
yields.
STRATEC Molecular will be released of its responsibilities if other sample materials than
described in the Intended Use are processed or if the sample preparation protocols are
changed or modified.
Principle and Procedure
Lysis
Samples are disrupted by using a mixer mill, bead mill or by mortar and pistil in combination
with liquid nitrogen. Afterwards, the disrupted material is lysed at denaturing non-chaotropic
conditions at elevated temperatures in presence of Lysis Buffer P and Proteinase K.
Because unlysed material has to be removed after lysis by filtration, the lysis procedure has
to be performed externally. The filtration step is required, because in most cases a
centrifugation step will not be able to remove very small debris, especially if a mortar and
pistil was used for disrupting.
Binding of the DNA
After addition of Binding Buffer A and SNAP Solution to the lysate, optimal binding
conditions are adjusted and the genomic DNA is bound to the magnetic particles.
Removing residual contaminants
Contaminants are efficiently removed using Wash Buffer I and Wash Buffer II, while the
DNA remains bound to the magnetic beads.
Elution
The DNA is finally eluted in Elution Buffer. The eluted DNA is ready-to-use in different
subsequent downstream applications like:
o PCR*, RAPD, AFLP analysis
o microsatellite analysis
o genotyping
o enzymatic restriction digestion
Yield and quality of genomic DNA
The amount of purified DNA derived by the InviMag® Plant DNA Mini Kit /KF96 procedure
from plant materials depends on the sample source, transport conditions, storage and
sample age.
The overall yield and quality of the isolated genomic DNA is suitable for any detection
system.

The PCR process is covered by US Patents 4,683,195, and 4,683,202 and foreign equivalents owned
by Hoffmann-La Roche AG.

Lysis Procedures
Protocol: Isolation of genomic DNA from up to 100 mg of plant material
Please read the instructions carefully and conduct the prepared procedure.
Homogenization of the starting material
Homogenize up to 100 mg of plant material by use of a pestle and mortar in combination with
liquid nitrogen. Commercially available equipment for homogenization (bead mill, etc.) can be
used too.
Transfer the homogenized starting material either into 1.5 ml reaction tubes (not provided) or
use a 96 DWP (not provided) and add 400 µl of Lysis Buffer P and 20 µl of Proteinase K to
each sample. Incubate the mixtures at 60°C for 30 min while continuously shaking.
During lysis, prefill all plates with the required buffers and appropriate volumes (see “Starting
a run”, page 12). After lysis, set up the Prefilter plate I onto the Binding Plate (2.0 ml Deep
Well Plate) and transfer the lysis mixtures into the filter plate. Incubate for 2-3 min at room
temperature or until all lysates have passed the filter plate. The lysed samples have now
been transferred into the Binding Plate.
Remove the filter plate and start the run on the KF instrument (see below).
Important: The kit will also co-purify RNA beside DNA. For the elimination of RNA (if required) add
20 µl RNase A (10 mg/ml) to the Lysis Buffer P prior before starting the lysis procedure.

Troubleshooting
Problem
Probable cause
Comments and suggestions
low amount of extracted
DNA
insufficient lysis
increase lyses time, but prevent
too long lyses time because this
also decreases the yield
Reduce amount of starting
material
incomplete elution
increase volume of Elution
Buffer / increase time of elution
step
low amount of SNAP Solution
mix SNAP Solution thoroughly
before addition
too much Elution Buffer
elute the DNA with a lower
volume of Elution Buffer
(don´t use less than 100 µl)
incorrect storage of starting
material
ensure that storage of starting
material is correct
avoid repeated freezing and
thawing cycles of the material
incorrect storage of starting
material
ensure that the storage of starting
material was correct
avoid multiple freezing and
thawing cycles of the sample
material
old material
ensure that the starting material is
fresh or stored at appropriate
conditions (long-term storage at
-20°C)
old material often contains
degraded DNA
ethanol carryover during elution
increase drying time for
evaporation of ethanol
salt carryover during elution
check the Wash Buffers for salt
precipitates. If any precipitates
are visible, solve them by
carefully warming up to 30°C
ensure that the Wash Buffers are
equilibrated at room temperature
small part of the magnetic
particles are left in the elution
centrifuge at full speed for 1 min
and transfer supernatant to a new
tube
low concentration of
extracted DNA
degraded / sheared
DNA
DNA does not perform
well in downstreamapplications (e.g. realtime PCR or PCR)
low A260:A280 ratio from

Appendix
KingFisher BindIt Software 3.2 or higher versions
BindIt software 3.2 or higher versions were and may be used to create assay files for the
KFmL, KF96/KFflex96 or KF-Duo instruments. The provided assay file(s) can either be
transferred onto the corresponding workstation(s) or be started directly from within the BindIt
software after assay import. Please keep in mind, that assay(s) run from within the BindIt
software are not stored in the workstation memory.
Important:
Be advised that BindIt SW 3.2 or higher versions use a new unique file extension.
Therefore, it is not possible to import assay files created with BindIt 3.2 or higher
versions into older BindIt software versions! Please ask your local Thermo Scientific
distributor for a software update.
Note:
When creating assay files for usage with KingFisher instruments in combination with
Microtiter Deep Well plates (e.g. Thermo Electron), it is essential to use the KingFisher
software 3.2 or higher versions for assay development because this software version
includes the correct adjustments for the microtiter plate. It is highly recommended to
use Thermo Microtiter Deep Well plates with KF96 / KFflex96 / KF-Duo workstations to
ensure the best purification result.

General notes on handling DNA
Nature of DNA
The length and delicate physical nature of DNA requires careful handling to avoid damage
due to shearing and enzymatic degradation. Other conditions that affect the integrity and
stability of DNA include acidic and alkaline environments, high temperature, and UV
irradiation. Careful isolation and handling of high molecular weight DNA is therefore required
to ensure compatibility with various downstream applications. Damaged DNA may perform
poorly in applications such as genomic Southern Blotting or long-template PCR.
Storage of DNA
A working stock of DNA can be stored at 2-8°C for several weeks. For long-term storage
DNA should be stored at -20°C, but storing at -20°C may cause shearing, particularly if the
DNA is exposed to repeated freezing and thawing cycles.
Note that the solution, in which the nucleic acid is eluted in, will affect it’s stability during
storage. Pure water lacks buffering capacity and an acidic pH may lead to acid hydrolysis.
Tris or Tris-EDTA buffer contains sufficient buffering capacity to prevent acid hydrolysis.
Drying, dissolving and pipetting DNA
Avoid overdrying of genomic DNA after ethanol precipitation. We highly recommend to air dry
than to use a vacuum, although vacuum drying can be used with caution.
Avoid vigorous pipetting. Pipetting of genomic DNA through small tip openings can cause
shearing or nicking. One way to decrease shearing of genomic DNA is to use special tips
that have wide openings designed for pipetting genomic DNA.
DNA yield
The amount of purified DNA from the plant material depends on sample source, transport
conditions, storage and age of the sample.
