Abstract A modification of the assay of cyclic nucleotide phosphodiesterase involving batch use of Dowex 1 anion exchange resin is described which allows for quantitative recovery of adenosine, guanosine, and their metabolites from the resin slurry. The assay described is suitable for use in crude preparations containing purine catabolizing enzymes. A standardized procedure for determining kinetic parameters of cyclic AMP hydrolysis is also discussed. This procedure was used in the partial characterization of the kinetics of cyclic AMP hydrolysis by rat and rabbit heart supernatant fractions.
