title: Localization of cyclic nucleotide phosphodiesterase activity within the bovine photoreceptor cell.
abstract: Cyclic nucleotide phosphodiesterase was measured in the outer layers of the bovine retina by quantitative histochemical methods. The outer segment region contained the highest specific enzyme activity. Phosphodiesterase activity with different kinetic properties was also observed in the outer plexiform layer.
