Anti-PCE-2 antibodies enable researchers to detect and measure the PCE-2 antigen in biological samples. This target is a reported synonym of the CES2 gene, which encodes carboxylesterase 2. This protein is known to function in metabolic processes, among other biological roles. The human version of PCE-2 has a canonical amino acid length of 559 residues and a protein mass of 61.8 kilodaltons. It is reported to be localized in the ER of cells and notably expressed in many tissues, such as the colon and duodenum. Other names for this target antigen include CE-2, CES2A1, and PCE-2. ELISA, Western Blot, and Immunohistochemistry are common applications for PCE-2 antibodies.
