Anti-PTPRE antibodies are used in the immunodetection of the protein protein tyrosine phosphatase receptor type E. In humans, the canonical protein has a reported length of 700 amino acid residues and a mass of 80.6 kDa. Its subcellular localization is in the cell membrane and cytoplasm. It is reported to be expressed in giant cell tumor (osteoclastoma rich in multinucleated osteoclastic cells). A member of the Protein-tyrosine phosphatase protein family, PTPRE is known to be involved with protein dephosphorylation. Synonyms for this target antigen include PTPE, R-PTP-EPSILON, receptor-type tyrosine-protein phosphatase epsilon, protein tyrosine phosphatase, receptor type, epsilon polypeptide, and HPTPE. PTPRE gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PTPRE antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Flow Cytometry, Immunofluorescence, and Immunohistochemistry are also common applications.
