13,14-dihydro-15-keto Prostaglandin E2-d9 (13,14-dihydro-15-keto PGE2-d9) is intended for use as an internal standard for the quantification of 13,14-dihydro-15-keto PGE2 by GC- or LC-MS. 13,14-dihydro-15-keto PGE2 is the primary metabolite of PGE2 in plasma.1 Endogenous or infused PGE2 is rapidly metabolized by the enzymes 15-hydroxy PGDH and 15-oxo-PG δ13-reductase to form 13,14-dihydro-15-keto PGE2. 13,14-dihydro-15-keto PGE2 accumulates to detectable levels; plasma levels in humans are between 10-100 pg/ml.2,3 It undergoes further metabolism and chemical decomposition, giving it a relatively short half-life. In dogs, the plasma half-life of 13,14-dihydro-15-keto PGE2 is about 9 minutes.3 In humans the metabolite has a similar short half-life, making it a poor choice of analytes for assays designed to measure total PGE2 biosynthesis.4,5
