Anti-PTPRH antibodies are used in the immunodetection of the protein protein tyrosine phosphatase receptor type H. In humans, the canonical protein has a reported length of 1115 amino acid residues and a mass of 122.4 kDa. Its subcellular localization is in the cell membrane, cell projections, and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably expressed at high levels in the brain, spleen and liver and at lower levels in the heart and stomach. A member of the Protein-tyrosine phosphatase protein family, PTPRH is reported to be a protein phosphatase that may contribute to contact inhibition of cell growth and motility by mediating the dephosphorylation of focal adhesion-associated substrates and thus negatively regulating integrin-promoted signaling processes. Synonyms for this target antigen include SAP1, stomach cancer-associated protein tyrosine phosphatase 1, transmembrane-type protein-tyrosine phosphatase type H, and R-PTP-H. A number of PTPRH antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, and Immunohistochemistry are also common applications.
