Anti-PBR-IP antibodies enable researchers to detect and measure the PBR-IP antigen in biological samples. This target is a reported synonym of the TSPOAP1 gene, which encodes TSPO associated protein 1. The human version of PBR-IP has a canonical amino acid length of 1857 residues and a protein mass of 200.1 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the mitochondria and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include BZRAP1, BZRAP1, and PBR-IP.
