block with intelliPATH Peroxidase Blocking Reagent (IPB5000) may be
performed following pretreatment.
Protocol Recommendations (Ventana BenchMark ULTRA):
Refer to the User Manual for specific instructions for use.
Recommended protocol parameters are as follows:
Template: U ultraView DAB
Pretreatment Protocol: ULTRA CC1 Standard (64 min) at 95°C
Primary Antibody: Incubate for 32 minutes at 37°C
ultraBlock (V-Blocker BRI4001): Incubate for 4 minutes (with
appropriate Option # registered by user)
V-Blocker is recommended to be applied prior to any detection system.
Detection: ultraView
Technical Note:
1. With cytokeratin markers, heat retrieval may provide a higher
sensitivity assay; whereas, enzyme digestion may produce greater
specificity. Users should validate the pretreatment method for their
specific application.
2. This antibody has been optimized for use with Biocare's MACH 4
Universal HRP-Polymer Detection and intelliPATH Universal HRP
Detection Kit. Use TBS for washing steps.
3. Protocol Recommendation for Ventana BenchMark XT available upon
The optimum antibody dilution and protocols for a specific application
can vary. These include, but are not limited to fixation, heat-retrieval
method, incubation times, tissue section thickness and detection kit
used. Due to the superior sensitivity of these unique reagents, the
recommended incubation times and titers listed are not applicable to
other detection systems, as results may vary. The data sheet
recommendations and protocols are based on exclusive use of Biocare
products. Ultimately, it is the responsibility of the investigator to
determine optimal conditions. The clinical interpretation of any
positiveor negative staining should be evaluated within the context of
clinical presentation, morphology and other histopathological criteria
by a qualified pathologist. The clinical interpretation of any positive or
negative staining should be complemented by morphological studies
Intended Use:
For In Vitro Diagnostic Use
Pan Cytokeratin [AE1/AE3] is a mouse monoclonal antibody cocktail
that is intended for laboratory use in the qualitative identification of a
broad spectrum of acidic and basic cytokeratin proteins by
immunohistochemistry (IHC) in formalin-fixed paraffin-embedded
(FFPE) human tissues. The clinical interpretation of any staining or its
absence should be complemented by morphological studies using
proper controls and should be evaluated within the context of the
patient’s clinical history and other diagnostic tests by a qualified
Summary and Explanation:
AE1/AE3 recognizes the acidic and basic (Type I and II) subfamilies of
cytokeratins. The cocktail of these two antibodies can be used to
detect most human epithelia. The acidic cytokeratins have molecular
weights of 56.5, 55, 51, 50, 50, 48, 46, 45, and 40 kDa. The basic
cytokeratins have molecular weights of 65-67, 64, 59, 58, 56 and 52
kDa. This pan cytokeratin antibody has proved useful as a screener for
the majority of human carcinomas.
Principle of Procedure:
Antigen detection in tissues and cells is a multi-step
immunohistochemical process. The initial step binds the primary
antibody to its specific epitope. A secondary antibody may be applied
to bind the primary antibody, followed by an enzyme labeled polymer;
or an enzyme labeled polymer may be applied directly to bind the
primary antibody. The detection of the bound primary antibody is
evidenced by an enzyme-mediated colorimetric reaction.

1. This antibody contains less than 0.1% sodium azide. Concentrations
less than 0.1% are not reportable hazardous materials according to
U.S. 29 CFR 1910.1200, OSHA Hazard communication and EC Directive
91/155/EC. Sodium azide (NaN3) used as a preservative is toxic if
ingested. Sodium azide may react with lead and copper plumbing to
form highly explosive metal azides. Upon disposal, flush with large
volumes of water to prevent azide build-up in plumbing. (Center for
Disease Control, 1976, National Institute of Occupational Safety and
Health, 1976) (5)
2. Specimens, before and after fixation, and all materials exposed to
them should be handled as if capable of transmitting infection and
disposed of with proper precautions. Never pipette reagents by mouth
and avoid contacting the skin and mucous membranes with reagents
and specimens. If reagents or specimens come into contact with
sensitive areas, wash with copious amounts of water. (6)
3. Microbial contamination of reagents may result in an increase in
nonspecific staining.
4. Incubation times or temperatures other than those specified may
give erroneous results. The user must validate any such change.
5. Do not use reagent after the expiration date printed on the vial.
