Anti-KRT19, CT (Keratin, Type I Cytoskeletal 19, Cytokeratin-19, CK-19, Keratin-19, K19)

KRT19 is a member of the keratin family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. The type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains. Unlike its related family members, this smallest known acidic cytokeratin is not paired with a basic cytokeratin in epithelial cells. It is specifically expressed in the periderm, the transiently superficial layer that envelopes the developing epidermis. Applications: Suitable for use in Immunofluorescence and Immunohistochemistry.
