Additional Information

Alternative name: Cytokeratin 17 / Keratin K17

Immunogen: E3 is a mouse monoclonal IgG2b antibody derived by fusion of X63 Ag 8.653 mouse myeloma cells with spleen cells from a Balb/c mouse immunized with a cytoskeletal preparation from rat colon.

Format: Purified

Isotype: IgG2b  (Matching secondary antibodies)

Clone: E3

Description: Cytokeratins are a subfamily of intermediate filament proteins and are characterized by a remarkable biochemical diversity, represented in human epithelial tissues by at least 20 different polypeptides. They range in molecular weight between 40 kDa and 68 kDa and isoelectric pH between 4.9 - 7.8. The individual human cytokeratins are numbered 1 to 20. The various epithelia in the human body usually express cytokeratins which are not only characteristic of the type of epithelium, but also related to the degree of maturation or differentiation within an epithelium. Cytokeratin subtype expression patterns are used to an increasing extent in the distinction of different types of epithelial malignancies. The cytokeratin antibodies are not only of assistance in the differential diagnosis of tumors using immunohistochemistry on tissue sections, but are also a useful tool in cytopathology and flow cytometric assays.

Specificity: Human and rat.

Application Details

Application Notes: E3 reacts with cytokeratin 17 in basal layers of pseudo-stratified and transitional epithelia. APPLICATIONS E3 is suitable for immunoblotting, immunocytochemistry, immunohistochemistry on frozen and paraffin-embedded tissues and flow cytometry. Optimal antibody dilution should be determined by titration, recommended range is 1:25 - 1:200 for flow cytometry, and for immunohistochemistry with avidin-biotinylated horseradish peroxidase complex (ABC) as detection reagent, and 1:100 - 1:1000 for immunoblotting applications.

Storage: Store at 4 o C, or in small aliquots at -20 o C.

Research Area: Extracellular Matrix

Restrictions: For Research Use only
