Description

Immunogen

human epidermal carcinoma A-431 and MCF-7 human breast cancer cell lines.

General description

Cytokeratin 18 (45 kDa) is the primary type I keratin expressed in simple epithelial cells. Epithelial cells and their derivatives characteristically contain intermediate filaments (IFs) composed of about 20 related polypeptides with molecular weights between 40,000-69,000. Each epithelial tissue has a specific and stable pattern of expression of some of these cytokeratin subunits. Epithelium derived tumors maintain the expression of the cytokeratins found in the normal tissue of origin. Therefore, carcinomas can be identified and classified by immunocytochemical staining with antibodies that react specifically with cytokeratins.

Mouse monoclonal clone CY-90 anti-Cytokeratin Peptide 18 antibody shows specific reactivity for the cytokeratin peptide 18 by immunoblotting analysis of human cultured cell lines as well as of human tissue extracts. The antibody reacts specifically with a wide variety of simple epithelia (e.g. intestine, respiratory and urinary systems, liver, and glandular epithelia). It does not react with stratified squamous epithelia (e.g. esophagus or epidermis) or with non-epithelial cells.

Application

Mouse monoclonal clone CY-90 anti-Cytokeratin Peptide 18 antibody is a homogenous population of antibody molecules that may be used for immunohistochemical staining of formalin fixed, paraffin-embedded or frozen tissue sections by means of indirect immunofluorescence or immunoperoxidase techniques.
