The K25 ELISA kits listed below utilize specific antibodies for the plate-based assay of K25 in various samples. K25 is another term for the KRT25 gene, which encodes the protein, keratin 25 in humans. It has been reported that K25 plays a role in pathways of aging and cytoskeleton organization, among other functions. Structurally, the KRT25 protein is described to be 450 amino acid residues in length and 49.3 kilodaltons in mass. It is localized to the cytoplasm of the cell. In terms of tissue specificity, it is reported to be highly expressed in skin and scalp, and weak expression observed in thymus and tongue. Other names for this target antigen include keratin, type I cytoskeletal 25 and CK-25.
