These K9 ELISA kits are immunodetection tools for measuring the levels of K9 in biological samples. K9 is an alias of the human KRT9 gene, which encodes the protein, keratin 9. Notably, K9 is known to play a role in epidermis development and epithelial cell differentiation, among other functions. The KRT9 protein is described to be 623 amino acid residues in length and 62.1 kilodaltons in mass. In terms of tissue specificity, it is reported to be expressed in the terminally differentiated epidermis of palms and soles. Other names for this target antigen include CK-9 and EPPK.
