title: [Transient photopotential of rhodopsin on a vesicle preparation of retinal rod membranes].
abstract: A potentiometric technique allowed us to observe and measure a photopotential of rhodopsin containing vesicles obtained from retinal disc membranes. The signal is proportional to the unbleached amount of rhodopsin in the sample, is photoreversible, related to some stages of photoconversion of the protein, and is nearly insensitive to modifications of physicochemical parameters.
