The protein encoded by the KRT19 gene 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. [RefSeq]

Optimal dilution of the Cytokeratin 19 antibody should be determined by the researcher.

A synthetic peptide specific to human Cytokeratin 19 / KRT19 was used as the immunogen for the Cytokeratin 19 antibody.

Store the Cytokeratin 19 antibody at -20oC.
