13,14-dihydro-15-keto Prostaglandin E2 (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.[1][2] 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.

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
