Anti-gastricsin antibodies enable researchers to detect and measure the gastricsin antigen in biological samples. This target is a reported synonym of the PGC gene, which encodes progastricsin. This protein is known to function in proteolysis, among other biological roles. The human version of gastricsin has a canonical amino acid length of 388 residues and a protein mass of 42.4 kilodaltons, although 2 isoforms have been identified. It is reported to be a secreted protein that is notably expressed in the stomach. Other names for this target antigen include PEPC and PGII. Western Blot is the most common application for the gastricsin antibodies listed below. ELISA and Immunohistochemistry are also common applications.
