Although a number of phospholipase A1s (PLA1s) have been identified in the recent decade, the physiological functions of PLA1s remain almost elusive. The major reason for this is the poor availability of assay methods. In many studies, radiolabeled phospholipid substrates have been used to measure PLA1 activity. This chapter describes the conventional PLA1 assay using a radiolabeled substrate and a novel PLA1 assay using electrospray ionization mass spectrometry.
