Anti-VPO2 antibodies enable researchers to detect and measure the VPO2 antigen in biological samples. This target is a reported synonym of the PXDNL gene, which encodes peroxidasin like. This protein is known to function in the response to oxidative stress, among other biological roles. The human version of VPO2 has a canonical amino acid length of 1463 residues and a protein mass of 163.7 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane, ER, cytoplasm, and is secreted of cells. VPO2 is a member of the Peroxidase protein family.
