Abstract:Abstract— Microvilli membrane fragments of squid (Todarodes pacificus) visual cells were adsorbed onto an oil surface in an aqueous medium. An electrical conductance increase was observed on illuminating the adsorbed film, and photopotential responses were recorded in a salt free medium of pH below 6, or in a saline of pH over 6. These electrical photoresponses are discussed in relation to the late receptor potential of squid retina.
“…Unfortunately, no definite conclusions can be stated until these systems are adequately characterized (Takagi, Azuma & Kishimoto, 1965;Takagi, 1980;Fesenko, Ratner & Lyvbarsky, 1976, Fesenko & Lyvbarsky, 1977Antanavage et al 1977).…”

Recent progress in membrane biology has brought us to a stage where it is possible to associate complex biological processes to identifiable membrane proteins. Technical advances in the biochemical characterization and purification of membrane proteins have contributed a wealth of structural information. The reconstitution approach has proved to be valuable in our efforts to understand the molecular mechanisms of membrane transport and energy transduction.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
