The K18 ELISA kits listed below utilize specific antibodies for the plate-based assay of K18 in various samples. K18 is another term for the KRT18 gene, which encodes the protein, keratin 18 in humans. It has been reported that K18 plays a role in the morphogenesis of anatomical structure and the cell cycle, among other functions. Structurally, the KRT18 protein is described to be 430 amino acid residues in length and 48.1 kilodaltons in mass. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is reported to be expressed in colon, placenta, liver and very weakly in exocervix. This protein is known to be glycosylated, cleaved and phosphorylated. Other names for this target antigen include CK-18, CK-18, and CYK18. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
