Anti-PTPRR antibodies are used in the immunodetection of the protein protein tyrosine phosphatase receptor type R. In humans, the canonical protein has a reported length of 657 amino acid residues and a mass of 73.8 kDa. Its subcellular localization is in the cell membrane, cytoplasm, and is secreted. Up to 4 different isoforms have been reported for this protein. It is notably expressed in cerebrospinal fluid. A member of the Protein-tyrosine phosphatase protein family, PTPRR is known to be involved with in utero embryonic development and protein dephosphorylation. Synonyms for this target antigen include PCPTP1, PTP-SL, PTPBR7, PTPRQ, receptor-type tyrosine-protein phosphatase R, Ch-1 PTPase, NC-PTPCOM1, and EC-PTP. PTPRR gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PTPRR antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
