Description
KRT19 is a type 1 keratin, an intermediate filament that provides structural support and has cell cycle regulatory functions in epithelial cells. KRT19 is a common epithelial marker with cytoplasmic positivity in immunohistochemistry. It is used to identify neoplastic epithelial cells in a number of cancers, including breast carcinomas, thyroid papillary carcinomas, cholangiocarcinomas, endometrial cancers, urothelial and collecting duct renal cancers, Paget’s disease, pancreatic cancers, and epithelial odontogenic tumors. Additionally, it is a putative cancer stem cell marker in hepatocellular carcinoma. In normal tissue, KRT19 is positive in epithelia of the breast, GI tract, kidney, bile ducts, pancreatic ducts, salivary and sweat glands, prostate epithelium, placental trophoblasts, uterus, and tonsillar squamous epithelium.

Immunogen
Recombinant full-length human KRT19 protein. Antigen Molecular Weight: 40 kDa
Specificity
This MAb reacts with the rod domain of human cytokeratin-19 (CK19), a polypeptide of 40 kDa . Its epitope maps between amino acid 312-335. 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.

Usage
Western Blotting (1-2 ug/ml) - Immunohistology (Formalin-fixed - 0.5-1 ug/ml for 30 min at RT - Staining of formalin-fixed tissues requires boiling tissue sections in 10 mM Citrate Buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.) Optimal dilution for a specific application should be determined.

10 mM PBS, 0.05% BSA, 0.05% Sodium Azide
Storage
Store at 2°C to 8°C for up to 2 years.
Restrictions
For research use only. Intended for use by laboratory professionals.
