This monoclonal antibody reacts with the rod domain of human cytokeratin-19 (CK19), a polypeptide of 40kD. Its epitope maps between aa312-335. CK19 is expressed in sweat gland, mammary gland ductal and secretory cells, bile ducts, gastrointestinal tract, bladder urothelium, oral epithelia, esophagus, and ectocervical epithelium. Anti-CK19 reacts with a wide variety of epithelial malignancies including adenocarcinomas of the colon, stomach, pancreas, biliary tract, liver, and breast. Perhaps the most useful application is the identification of thyroid carcinoma of the papillary type, although 50%-60% of follicular carcinomas are also labeled. Anti-CK19 is a useful marker for detection of tumor cells in lymph nodes, peripheral blood, bone marrow and breast cancer. Applications: Suitable for use in ELISA, Western Blot, Flow Cytometry, Immunoprecipitation, Immunofluorescence and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 0.5-1ug/ml Flow Cytometry: 0.5-1ug/10e6 cells Immunofluorescence: 1-2ug/ml Immunoprecipitation: 1-2ug/500ug protein lysate Immunohistochemistry (Frozen & Formalin fixed paraffin embedded): 0.5-1ug/ml/30min @ RT Optimal dilutions to be determined by the researcher. Positive Control: MCF-7, HeLa, Hep-G2 cells, Breast Cancer Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
