Anti-PPP3R1 antibodies are used in the immunodetection of the protein protein phosphatase 3 regulatory subunit B, alpha. In humans, the canonical protein has a reported length of 170 amino acid residues and a mass of 19.3 kDa. Its subcellular localization is in the cell membrane and cytoplasm. It is notably widely expressed in many tissue types. A member of the Calcineurin regulatory subunit protein family, PPP3R1 is a regulatory subunit of calcineurin, a calcium-dependent, calmodulin stimulated protein phosphatase. Synonyms for this target antigen include CNB, CNB1, calcineurin subunit B type 1, calcineurin B, type I (19kDa), protein phosphatase 2B regulatory subunit 1, and CALNB1. PPP3R1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of PPP3R1 antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA, Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
