Human Cytokeratin 8/KRT8 PharmaGenie ELISA Kit (SBRS0815)

Cytokeratin 8 (KRT8) is a type II intermediate filament protein of approximately 53 kDa that forms heterodimers with its partner KRT18 to build the cytoskeletal network of simple epithelia. KRT8 is widely investigated as a biomarker of epithelial tumors, including hepatocellular, breast, and colorectal carcinomas, and circulating fragments are studied as candidate disease markers. This Assay Genie kit enables quantitative measurement of KRT8 across cell culture supernatants and blood-derived samples, supporting studies of epithelial differentiation, tumor progression, and cytoskeletal remodeling. Researchers commonly apply the assay to monitor epithelial-mesenchymal transition, apoptotic responses, and hepatocyte injury models, complementing immunohistochemistry and western blot workflows that validate expression at the protein level.
