Human anti Human cytokeratin 19 antibody, clone AbD03765 recognizes human cytokeratin 19 (CK19), which is the smallest acidic type I intermediate filament with a molecular weight of 40 kDa. The intermediate filaments are generally expressed as heterodimers at the cell surface. CK19 is often co-expressed with cytokeratin 8 (CK8). Cytokeratin 19 is widely expressed in simple epithelium, the basal cells of squamous epithelium and some carcinomas.
