The K20 ELISA kits listed below utilize specific antibodies for the plate-based assay of K20 in various samples. K20 is another term for the KRT20 gene, which encodes the protein, keratin 20 in humans. It has been reported that K20 plays a role in the apoptotic pathway and epithelial cell differentiation, among other functions. Structurally, the KRT20 protein is described to be 424 amino acid residues in length and 48.5 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 the intestinal epithelium. This protein is known to be cleaved and phosphorylated. Other names for this target antigen include CD20, CK-20, and CK20. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
