Cytokeratin 9-19 antibody

Antigen: Cytokeratin 9-19

Clonality: Monoclonal (AE1)

Host: Mouse

Reactivity: Human

Application: Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))

Catalog no.: ABIN98141

Additional Information

Immunogen: BALB/C mice were immunized with human epidermal keratin.

Format: Ig-fraction

Isotype: IgG1-kappa  (Matching secondary antibodies)

Clone: AE1

Specificity: This antibody recognizes most of the acidic (Type I) keratins. It recognizes keratin polypeptides of 50 and 56.5 kD. In keratinized epidermis, 50 kD keratin is present in the basal layer, while 56.5 kD keratin is present in suprabasal layers. This antibody can be used to stain distinct cell layers in an epithelial tissue and various neoplasms of epithelial origin.

Application Details

Application Notes: Titer/Working Dilution: This antibody may be diluted to a titer of 1:50-1:100 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 minutes at room temperature. However, depending upon the fixation conditions and the staining system employed, optimal incubation should be determined by the user. Enzymatic predigestion of paraffin embedded tissues is recommended prior to the immunostaining. Positive Control: Skin. Cellular localization: Cytoplasm

Concentration: 100ug/ml approximately

Buffer: This antibody is supplied as purified IgG fraction harvested from ascites and contains 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
