Anti-PTGIR antibodies are used in the immunodetection of the protein prostaglandin I2 receptor. In humans, the canonical protein has a reported length of 386 amino acid residues and a mass of 41 kDa. Its subcellular localization is in the cell membrane. A member of the G-protein coupled receptor 1 protein family, PTGIR is a known receptor for prostacyclin (prostaglandin I2 or PGI2). Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include PRIPR, prostacyclin receptor, PGI receptor, PGI2 receptor, prostaglandin I2 (prostacyclin) receptor (IP), and IP. PTGIR gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of PTGIR antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
