Abstract
A non-radioactive, spectrophotometric, microtiter plate assay for human cystolic phospholipase A.sub.2 (cPLA.sub.2) is described. The assay utilizes a novel synthetic thiol-phospholipid analog as a substrate. In one embodiment, the substrate is a phosphatidylcholine derivative with an arachidonoylthioester in the sn-2 position and an alkenyl-ether or alkenyl-ether in the sn-1 position. The alkyl-ether and the alkenyl-ether in the sn-1 position of the substrate ensures that the assay will only measure cPLA.sub.2 activity and will not be complicated by metabolism of the lysophospholipid product by the enzyme's and lysophospholypase activity.
