Isoprostanes are prostaglandin (PG)-like compounds produced in vivo by free radical-catalyzed peroxidation of arachidonoyl-containing lipids. 8-iso Prostaglandin A2-biotin (8-iso PGA2-biotin) is an affinity probe which allows 8-iso PGA2 to be detected through an interaction with the biotin ligand. Biotinylated eicosanoids have been used to capture proteins which interact with the lipid.1WARNING This product is not for human or veterinary use.
