Anti-K222 antibodies enable researchers to detect and measure the K222 antigen in biological samples. This target is a reported synonym of the TIMP3 gene, which encodes TIMP metallopeptidase inhibitor 3. This protein is known to function in cytokine-mediated signaling pathways, among other biological roles. The human version of K222 has a canonical amino acid length of 211 residues and a protein mass of 24.1 kilodaltons. It is reported to be localized in the extracellular matrix and is secreted of cells. Other names for this target antigen include HSMRK222 and K222TA2. Western Blot is the most common application for the K222 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
