Abstract
To evaluate phospholipase A activity a new assay is suggested. This assay is based on the recording of boundary potential of the planar bilayer during enzymatic hydrolysis of lipids. To register these changes, a second harmonic method is used. Sensitivity of the assay is about 0.0002 units/ml regardless of the impurities that may be present in the samples. On eanalysis takes about 5 min.
