title: Localization of cholecystokinin immunoreactivity in amacrine cells of the retina.
abstract: The distribution of cholecystokinin-like immunoreactivity within frog retina was studied by immunofluorescence. Positive staining for cholecystokinin was observed in the somata of some amacrine cells and their processes within the inner plexiform layer. Chromatography of frog retinal extracts on Sephadex G-50 and parallel dilution curves show that the retinal cholecystokinin-like immunoreactivity was also found to be associated with human and bovine retinas but absent from other ocular tissue.
