Description

Recognizes a protein of 40kDa, identified as cytokeratin-19 (CK19), which 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.

Application Notes

Optimal dilution of the recombinant KRT19 antibody should be determined by the researcher.

Immunogen

Recombinant full-length human KRT19 protein was used as the immunogen for the recombinant KRT19 antibody.

Storage

Aliquot the recombinant KRT19 antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
