15-deoxy-Δ12,14-Prostaglandin D2-d4 (15-deoxy-Δ12,14-PGD2-d4) is an internal standard for the quantification of 15-deoxy-Δ12,14-PGD2 (Item No. 12700) by GC- or LC-MS. 15-deoxy-Δ12,14-PGD2 is a metabolite of PGD2 (Item No. 12010).1 It is an agonist of PGD2 receptor 2 (DP2) that binds DP2 (Ki = 50 nM for the mouse receptor expressed in HEK293 cell membranes) and induces activation of eosinophils (EC50 = 8 nM).2,3 It also stimulates the recruitment of steroid receptor coactivator-1 (SRC-1) to peroxisome proliferator-activated receptor γ (PPARγ) and induces PPARγ-mediated transcription in a reporter assay when used at a concentration of 5 µM.1 15-deoxy-Δ12,14-PGD2 is cytotoxic to L1210 murine leukemia cells (IC50 = 0.3 µg/ml).4 It inhibits ADP-induced platelet aggregation (IC50 = 320 ng/ml) less potently than PGD2.5WARNING This product is not for human or veterinary use.
