Anti-PTPRA antibodies are used in the immunodetection of the protein protein tyrosine phosphatase receptor type A. In humans, the canonical protein has a reported length of 802 amino acid residues and a mass of 90.7 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Protein-tyrosine phosphatase protein family, PTPRA is known to be involved with protein dephosphorylation and protein phosphorylation. Synonyms for this target antigen include HLPR, HPTPA, HPTPalpha, LRP, PTPA, PTPRL2, R-PTP-alpha, and HEPTP. PTPRA gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PTPRA 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.
