Product Information

Intended Use:

In Vitro Diagnostic (IVD). Use in immunohistochemistry (IHC) test methods only.

The monoclonal antibody 34βE12 is used for the in vitro examination of human biological samples using immunohistochemistry (IHC) methods for the qualitative identification of Cytokeratin. The clinical interpretation of any staining or its absence should be complemented by morphological studies and proper controls and should be evaluated within the context of the patient's clinical history and other diagnostic tests by a qualified pathologist.

Reactivity
Human
Immunogen
It was developed using a solubilized keratin extracted from human stratum corneum.
Formulation
Phosphate-buffered solution with BSA + 0.1% NaN3.
Preparation
Tissue Culture Supernatant
Storage & Handling
Store between 2°C and 8°C.
Recommended Usage

Each lot of this antibody is quality control tested by immunohistochemical staining.

The optimal working dilution should be determined for each specific assay condition.
IHC: ready-to-use

Positive tissue (human): Human tonsil, breast, prostate

Tissue Sections: Formalin-fixed, paraffin-embedded tissues and acetone-fixed cryostat sections
Pretreatment: For optimal staining, the sections should be pretreated with an antigen unmasking solution such as Retrieve-All 1 (Cat. No. 927901).
Incubation: 60 minutes at room temperature for Biotin based detection systems such as USA Ultra Streptavidin Detection (Cat. No. 929501)
