Anti-PTPN18 antibodies are used in the immunodetection of the protein protein tyrosine phosphatase non-receptor type 18. In humans, the canonical protein has a reported length of 460 amino acid residues and a mass of 50.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in the brain, colon and several tumor-derived cell lines. A member of the Protein-tyrosine phosphatase protein family, PTPN18 is known to be involved with protein dephosphorylation. Synonyms for this target antigen include PTP-HSCF, tyrosine-protein phosphatase non-receptor type 18, brain-derived phosphatase, protein tyrosine phosphatase, non-receptor type 18 (brain-derived), and BDP1. PTPN18 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. A number of PTPN18 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
