描述

一般說明

Monoclonal Anti-Cytokeratin Peptide 19 (mouse IgG2a isotype) is derived from the A53-B/A2 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with mammary human carcinoma cell line MCF-7. Monoclonal Anti-Cytokeratin Peptide 19, known as clone A53-B/A2, or clone No. Ks 19.1, reacts with the rod domain of human cytokeratin peptide 19 (40 kDa), a cytoskeletal protein restricted to epithelial and carcinoma cells. Cytokeratin 19 is a member of the type I acidic subfamily. It is differentially expressed in various human tissues.

特異性

Also cited as clone no. KS 19.1, the antibody reacts with the rod domain of cytokeratin peptide 19, a cytoskeletal protein restricted to epithelial and carcinoma cells. Species cross-reactivity is low or absent. The antibody labels simple epithelia and basal cells of non-cornifying stratified squamous epithelia. It is a useful tool in discriminating simple carcinomas from those of different origin and for carcinoma subtyping. This antibody has also been shown to be a marker of pre-malignant lesions of the oral epithelium.

免疫原

human mammary carcinoma cell line MCF-7.

應用

Monoclonal Anti-Cytokeratin Peptide 19 antibody produced in mouse is also suitable:

• for immunoblotting, for immunocytochemistry,
• for immunofluorescence,
• as a marker of premalignant lesions of the oral epithelium, to label cytokeratin in formalin-fixed or Carnoy-fixed, paraffin embedded tissue and in frozen sections of human tissue, to label simple epithelia and basal cells of noncornifying stratified squamous epithelia.

Monoclonal Anti-Cytokeratin Peptide 19 antibody produced in mouse is suitable for microarray and indirect immunofluorescence at a dilution of 1:50 using formalin-fixed, paraffin-embedded and human tissue sections.

生化／生理作用

Keratin, type I cytoskeletal 19 (40kDa protein) is also known as cytokeratin-19 (CK-19) or keratin-19 (K19). It is encoded by the KRT19 gene in humans. Keratin 19 is a type I keratin. Keratins are intermediate filament-forming proteins that provide mechanical support and perform a variety of additional functions in epithelial cells. K19 is expressed in a subset of hepatocellular carcinomas (HCC) with poor prognosis and is considered as a biliary/hepatic progenitor cell (HPC) marker. It is also a predictor of poorer prognosis for patients with human lung squamous cell carcinoma (SCC).

Monoclonal anti-cytokeratins are specific markers of epithelial cell differentiation and have been widely used as tools in tumor identification and classification.
