FIELD: biochemistry. SUBSTANCE: phospholipase D activity is determined by phosphatidic acid quantity formed after enzymatic hydrolysis of phosphatidylcholine with phospholipase D. Phosphatidylcholine hydrolysis is performed by treatment of samples with dye Victoria Blua R in aqueous saturated solution of urea. Stained complex of phosphatidic acid is separated for phases. Quantity of phosphatidic acid formed is determined by spectrophotometry method in organic phase. EFFECT: improved method of assay. 1 dwg
