Anti-PPFIA2 antibodies are used in the immunodetection of the protein PTPRF interacting protein alpha 2. In humans, the canonical protein has a reported length of 1257 amino acid residues and a mass of 143.3 kDa. Its subcellular localization is in the cytoplasm. Up to 8 different isoforms have been reported for this protein. It is found to be preferentially expressed in the brain. A member of the Liprin protein family, PPFIA2 is known to be involved with cell matrix adhesion. Synonyms for this target antigen include protein tyrosine phosphatase, receptor type, f polypeptide (PTPRF), interacting protein (liprin), alpha 2, and liprin-alpha-2. PPFIA2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some PPFIA2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry and Immunofluorescence are also common applications.
