Technical Data
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.

Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications have not been tested.

Recommended Dilutions:
Western Blot: 1:1000
Immunohistochemistry (FFPE): 1:50-1:100
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
