Cytokeratin 19 Antibody (KRT19/800) Summary

Immunogen
Recombinant full-length human Cytokeratin 19 protein. (Uniprot: P08727 )
Localization
Cytoplasmic
Marker
Pancreatic Stem Cell Marker
Specificity
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.

Applications/Dilutions

Dilutions
  • Flow (Intracellular)
  • Flow Cytometry 0.5-1 ug/million cells
  • Immunocytochemistry/Immunofluorescence 1-2 ug/ml
  • Immunohistochemistry
  • Immunohistochemistry-Paraffin 1-2 ug/ml
  • Western Blot 1-2 ug/ml
Application Notes
Immunohistochemistry (Formalin-fixed): 1-2ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes.
Optimal dilution for a specific application should be determined.
Theoretical MW
40 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background

Cytokeratin 19 (also known as Keratin, type I cytoskeletal 19) belongs to the keratin family which consists of fibrous proteins that make up the framework of epithelial cells. Cytokeratin 19 plays a role in the organization of myofibers. This protein is known to have interactions with ZNF638, FANCG, FAM107A, KRT15 and EXOC8. Cytokeratin 19 has been studied in relation to several disorders and diseases including chordoma, adenoma, hamartoma, adenoiditis, carcinoma, and liver disease.
