Merck, C2562-.2ML, Monoclonal Anti-Cytokeratin, pan (Mixture) antibody produced in mouse

Monoclonal Anti-Cytokeratin, pan (mouse IgG1 and IgG2a isotypes) is a mixture of monoclonal antibodies from the following clones: C-11, PCK-26, CY-90, KS1A3, M20, and A53-B/A2. Cytokeratins, a group comprising at least 29 different proteins, are characteristic of epithelial and trichocytic cells. Cytokeratins 1 (68 kDa), 4 (59 kDa), 5 (58 kDa), 8 (52 kDa), and 6 (56 kDa) are members of the type II neutral-to-basic subfamily expressed in cornified epithelia, non-cornified stratified squamous epithelia, stratified epithelia, simple epithelia and in tissues with natural or pathological turnover respectively. Cytokeratins 10 (56 kDa), 13 (54 kDa, and 18 (45 kDa) are members of the type I acidic subfamily expressed in cornified epithelia, non-cornified stratified squamous epithelia and simple epithelial cells respectively. Cytokeratin peptide 19 (40 kDa) is a type I keratin which can be expressed in both simple and in broad cells of stratifying epithelia at specific sites.
