Diheptanoyl Thio-PC is a substrate for all phospholipase A2s (PLA2s) with the exception of cPLA2 and PAF-acetyl hydrolase (PAF-AH).1 Interaction of this compound with a PLA2 results in cleavage of the sn-2 fatty acid generating a free thiol on the lysophospholipid. This free thiol can be detected using chromogenic substrates such as DTNB (Ellman’s reagent) and DTP.2,3
