An isoelectric focusing technique was used to isolate multiple forms of cyclic nucleotide phosphodiesterase from a 105 000 times g soluble supernatant fraction of sonicated rat cerebrum. These separated peaks of activity had iso-electric points of 5.1, 5.6, 6.0, 6.6, 8.0, and 9.0. The activities were not stimulated by an endogenous activator of the enzyme but were inhibited by EGTA treatment. However, activator-sensitive forms of the enzyme could be separated from brain if the preparation of rat cerebrum was dialyzed against an EGTA containing buffer prior to electrofocusing. The procedure was also used to isolate a column fraction that stimulated maximum velocities of cyclic AMP and cyclic GMP hydrolysis. This fraction was itself devoid of phosphodiesterase activity and had an isoelectric point of 4.7.
