Product Specifications

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 for Cytokeratin 19 Antibody (KRT19/800)

Application
Recommended Usage

Flow Cytometry

0.5-1 ug/million cells

Immunocytochemistry/ Immunofluorescence

1-2 ug/ml

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.

Background: Cytokeratin 19

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.
