Anti-PTGR2 antibodies are used in the immunodetection of the protein prostaglandin reductase 2. In humans, the canonical protein has a reported length of 351 amino acid residues and a mass of 38.5 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the NADP-dependent oxidoreductase L4BD protein family, PTGR2 is known to function as 15-oxo-prostaglandin 13-reductase and acts on 15-keto-PGE1, 15-keto-PGE2, 15-keto-PGE1-alpha and 15-keto-PGE2-alpha with highest activity towards 15-keto-PGE2. Synonyms for this target antigen include 15-oxoprostaglandin-delta13-reductase, PRG-2, epididymis secretory protein Li 298, epididymis secretory sperm binding protein, and 15-oxoprostaglandin 13-reductase. PTGR2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are common applications for PTGR2 antibodies.
