Anti-APP2 antibodies enable researchers to detect and measure the APP2 antigen in biological samples. This target is a reported synonym of the XPNPEP2 gene, which encodes X-prolyl aminopeptidase 2. This protein is known to function in proteolysis, among other biological roles. The human version of APP2 has a canonical amino acid length of 674 residues and a protein mass of 75.6 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in the rectum, kidney, duodenum, colon, and appendix. Other names for this target antigen include AEACEI and xaa-Pro aminopeptidase 2. Indicated applications for APP2 antibodies listed below include Western Blot and Immunohistochemistry.
