Cytokeratin 14 Antibody / CK14 / KRT14

• Catalog Number: orb248446
• Category: Antibodies
• Description: Cytokeratin 14 (CK14) belongs to the type I (or A or acidic) subfamily of low molecular weight keratins and exists in combination with keratin 5 (type II or B or basic). Cytokeratin 14 is found in basal cells of squamous epithelia, some glandular epithelia, myoepithelium, and mesothelial cells. antibody to cytokeratin 14 is useful in differentiating squamous cell carcinomas from poorly differentiated epithelial tumors. cytokeratin 14 antibody is one of the specific basal markers for distinguishing between basal and non-basal subtypes of breast carcinomas. Cytokeratin 14 antibody is also a good marker for differentiation of intraductal from invasive salivary duct carcinoma by the positive staining of basal cells surrounding the in-situ neoplasm as well as for differentiation of benign prostate from prostate carcinoma. Furthermore, this antibody has been useful in separating oncocytic tumors of the kidney from its renal mimics, and in identifying metaplastic carcinomas of the breast.

• Note: For research use only
• Application notes: The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the antibody to be titered up or down for optimal performance.1. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM Citrate Buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
• Expiration Date: 12 months from date of receipt.
