		Technical Data
K0199-05B	KRT4, CT (Keratin, Type II Cytoskeletal 4, Cytokeratin-4, CK-4, Keratin-4, K4, CYK4, Type-II Keratin Kb4)

Description:
The protein is a member of the keratin family. The type II cytokeratins consist of basic or neutral proteins which are arranged in pairs of heterotypic keratin chains coexpressed during differentiation of simple and stratified epithelial tissues. This type II cytokeratin is specifically expressed in differentiated layers of the mucosal and esophageal epithelia with family member KRT13.

Applications:
Suitable for use in ELISA, Western Blot, and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
ELISA: 1:1,000
Western Blot: 1:50-1:100
Immunohistochemistry: 1:50-1:100
Optimal dilutions to be determined by the researcher.
