Immunogen Human keratin K18 from HeLa cytoskeletal preparation
Clone Ks18-04
Isotype IgG1
Specificity Ks 18.04 represents an excellent marker to discriminate simple epithelia from those of different origin. Tumors specifically detected: all adenocarcinoma, mammary carcinoma, urinary bladder carcinoma, undifferentiated carcinoma, cervix carcinoma, hepatocellular carcinoma. Polypeptide reacting: Mr 45 000 polypeptide (human keratin K18) of all simple type epithelia and basal cells of many squamous, nonepidermal epithelia. Reactivities on cultured cell lines (tested so far): HeLa and MCF-7
Cross-Reactivity (Details) Species reactivity (tested):Human, Mouse, Rat, Bovine, Porcine, Canine, Hamster, Sheep, Fish (Trout) and Zebrafish
Purification Protein A chromatography
Alternative Name Cytokeratin 18
Background Cytokeratin 18 is an acidic keratin which is found primarily in non squamous epithelia and is present in a majority of adenocarcinomas and ductal carcinomas but not in squamous cell carcinomas. Cytokeratin 18 exists in combination with Cytokeratin 8, a basic keratin. Hepatocellular carcinomas have been reportedly defined by the use of antibodies that recognize only Cytokeratins 8 and 18.Synonyms: CK18, CYK18, Cell proliferation-inducing gene 46 protein, Cytokeratin-18, K18, KRT18, Keratin 18, Keratin type I cytoskeletal 18, Keratin-18
