Mouse anti Human cytokeratin 19 antibody, clone A53-B/A2 recognizes the rod domain (aa 312-335) of human cytokeratin 19 (Böttger; et al. 1995) also known as keratin 19 encoded by the KRT19 gene. Cytokeratin 19 is a 400 amino acid intermediate filament protein lacking a C-terminal tail domain, in contrast to all other intermediate filament proteins.

Cytokeratin 19 expression is observed in striated muscle where it is involved in forming the association between the contractile apparatus and dystrophin (Stone et al. 2005). Expression is also seen in many ductal and glandular cells together with a restricted set of normal and neoplasic epithelial cells.

Mouse anti Human cytokeratin 19 antibody, clone A53-B/A2 detects a band of ~45 kDa in western blotting using an A-549 human alveolar adenocarcinoma cell line lysate.
