A review on methods of phospholipase A determination.

A short review is presented on methods to determine phospholipase A activities. On purpose, only those methods are covered which can, at least potentially, be used for assaying the low activities generally associated with intracellular phospholipases A. A selection was made of procedures which apply non-radioactive or radioactive substrates or chemically modified substrate analogs which can be used for spectrophotometric assays.
