The K15 ELISA kits listed below are analytical tools for measuring concentrations of K15 in various samples. K15 is an alternative name for the human KRT15 gene, which encodes the protein, keratin 15. It has been mentioned that K15 plays a role in epidermis development and epithelial cell differentiation, among other functions. Structurally, the KRT15 protein is 456 amino acid residues in length and 49.2 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. In terms of tissue specificity, it is reported to be expressed in a discontinuous manner in the basal cell layer of adult skin epidermis, but continuously in the basal layer of fetal skin epidermis and nail. Other names for this target antigen include CK15 and K1CO. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
