Product Description
tetranor-Prostaglandin E metabolite (tetranor-PGEM) is the major urinary metabolite of PGE1 and PGE2, and is used as a urinary marker of PGE2 biosynthesis. About 15% of an infused dose of PGE2 appears as this metabolite in the urine of humans. Normal healthy males excrete 7-40 µg of tetranor-PGEM over a 24-hour period
