Keratin1-19 antibody

Antigen: Keratin1-19

Clonality: Monoclonal (AE1-AE3)

Host: Mouse

Reactivity: Human

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

Catalog no.: ABIN98106

Additional Information

Alternative name: Cytokeratin 1-19

Immunogen: BALB/c mice were immunized with human epidermal keratins.

Format: Supernatant (prediluted)

Isotype: IgG1 kappa  (Matching secondary antibodies)

Clone: AE1-AE3

Specificity: This AE1/AE3 antibody cocktail recognizes most of the acidic (Type I) keratins as well as basic (Type II). It recognizes keratin polypeptides of 40, 48, 50, 52, 54, 56.5, 58, 59 and 64 to 67 kD. In keratinized epidermis, 50 kD keratin is present in the basal layer, while 56.5 kD keratin is present in suprabasal layers, where as 58 kD keratin is present in the basal and suprabasal layers, while 65 to 67 kD keratin is present in the cells above the basal 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: 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. Proteolytic treatment is required prior to immunostaining of formalin fixed paraffin embedded tissue sections. Positive Control: Skin. Cellular localization: Cytoplasmic

Concentration: 1 to 4 ug/ml

Buffer: This antibody has been pretitered and quality controlled to work on formalin-fixed paraffin-embedded as well as acetone fixed cryostat tissue sections. No further titration is required.

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
