Anti-CCPI antibodies enable researchers to detect and measure the CCPI antigen in biological samples. This target is a reported synonym of the GZMB gene, which encodes granzyme B. This protein is known to function in the apoptotic pathway, among other biological roles. The human version of CCPI has a canonical amino acid length of 247 residues and a protein mass of 27.7 kilodaltons. It is reported to be a secreted protein that is notably expressed in the spleen, skin, and bone marrow. Other names for this target antigen include C11 and CGL-1. A number of CCPI antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
