Anti-PPP2R3A antibodies are used in the immunodetection of the protein protein phosphatase 2 regulatory subunit B''alpha. In humans, the canonical protein has a reported length of 1150 amino acid residues and a mass of 130.3 kDa. Up to 3 different isoforms have been reported for this protein. It is found to be expressed in the heart, brain, placenta, lung, muscle and kidney. PPP2R3A is known to be involved with the Wnt signaling pathway. Synonyms for this target antigen include PR130, PR72, serine/threonine-protein phosphatase 2A regulatory subunit B'' subunit alpha, PR130/B''alpha1 subunit, and PPP2R3. PPP2R3A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PPP2R3A antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA, Western Blot, and Immunofluorescence are also common applications.
