Anti-protease, serine 27 antibodies enable researchers to detect and measure the protease, serine 27 antigen in biological samples. This target is a reported synonym of the PRSS27 gene, which encodes serine protease 27. This protein is known to function in proteolysis, among other biological roles. The human version of protease, serine 27 has a canonical amino acid length of 290 residues and a protein mass of 31.9 kilodaltons. It is reported to be a secreted protein that is notably expressed in the esophagus and tonsil. Other names for this target antigen include channel-activating protease 2, marapsin, and pancreasin. Immunocytochemistry is the most common application for the protease, serine 27 antibodies listed below. ELISA and Immunofluorescence are also common applications.
