Keratin 5/14 (KRT5/14) antibody

Antigen: Keratin 5/14 (KRT5/14)

Clonality: Monoclonal (XM26-LL002)

Host: Mouse

Reactivity: Human

Application: Immunohistochemistry (IHC)

Catalog no.: ABIN125230

Additional Information

Alternative name: Cytokeratin 5 & 14

Immunogen: XM26: prokaryotic recombinant protein corresponding to 103 amino acid portion of C-terminal region of the human cytokeratin 5 molecule. LL002: Synthetic peptide of the extreme c-terminal of human keratin-14.

Isotype: IgG1, IgG3  (Matching secondary antibodies)

Clone: XM26-LL002

Specificity: This antibody cocktail reacts with cytokeratin 5 intermediate filament protein as well as to 50 kD cytokeratin protein designated cytokeratin 14. Basal cells of human epidermis express acidic cytokeratin 14 and basic cytokeratin 5. Cytokeratin 5 is a 58 kD protein, which is closely related to cytokeratin 6. Cytokeratin 5 and 6 are expressed in basal cell epithelioma, basal cells of prostate, urothelium, vagina, squamous cell carcinomas of skin, tongue, epiglottis and rectal-anal region. Cytokeratin 5 can be useful in the distinction of mesotheliomas from most adenocarcinomas. Cytokeratin 14 belongs to the type A (acidic) subfamily of low MW cytokeratins and exists in combination with cytokeratin 15. This antibody can be useful to distinguish stratified epithelial cells from simple epithelial cells.

Application Details

Application Notes: Titer/Working Dilution: This antibody may be diluted to a titer of 1:25-1:75 in an ABC method. However, depending on the staining conditions employed, we suggest that final dilution should be determined by the user. Staining Protocol: We suggest an incubation period of 30 to 60 minutes at room temperature. However, depending upon the fixation conditions and the staining system employed, optimal incubation should be determined by the user. Formalin fixed paraffin embedded tissue sections require high temperature antigen unmasking with 10 mM citrate buffer, pH 6.0 prior to immunostaining. Positive Control: Skin. Cellular localization: Cytoplasmic

Concentration: 100ug/ml approximately

Buffer: This antibody is supplied as liquid cocktail of Cytokeratin 5 & 14 containing sodium azide as preservative.

Storage: Store the antibody at 2-8o c. Do not use it beyond the expiration date stated on the label.

Research Area: Extracellular Matrix

Restrictions: For Research Use. CE-certified for In Vitro Diagnostics (IVD) Use in the European Union
