Anti-P2RX5 antibodies are used in the immunodetection of the protein purinergic receptor P2X 5. In humans, the canonical protein has a reported length of 422 amino acid residues and a mass of 47.2 kDa. Its subcellular localization is in the membrane. Up to 5 different isoforms have been reported for this protein. It is notably expressed at high levels in the brain and immune system. A member of the P2X receptor protein family, P2RX5 is a known receptor for ATP that acts as a ligand-gated ion channel. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include P2X5, P2X5R, P2X purinoceptor 5, ATP receptor subunit, ionotropic ATP receptor P2X5, and LRH-1. P2RX5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of P2RX5 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
