Description and applications

Mouse antibody against Human Keratin 8 (Subclass: IgG2b)

Keratins are a family of intermediate filament proteins that assemble into filaments through forming heterodimers of one type I keratin (keratins 9 to 23) and one type II keratin (keratins 1 to 8). Keratins demonstrate tissue and differentiation specific expression profiles. Keratins 8 and 18 are two of the first keratins expressed in the embryo, and persist into adult tissues as the keratin pair representing minimal epithelial keratin expression. Keratins 8 and 18 are major components of all simple epithelia (but not of stratified squamous epithelia) and adenocarcinomas. Keratin 8 is the tissue polypeptide antigen (TPA) reported to be present in the serum of cancer patients.

Applications:  IHC IF WB
