Investigation of Dynamic Behaviors of Asialoglycoprotein Receptors of Hepatocytes Using a Latex Probe Whose Surface Was Coated with Lactose-Carrying Polystyrene

Characteristic properties of oligosaccharide-substituted poly styrenes as a hepatocyte-specific culture substratum were investigated from the viewpoint of adsorption and recognition. X-ray photoelectron spectra sug gest that the adsorption of the polymer onto a polystyrene film occurred in near mono-molecular layer thickness of 10-25 A in globular conformations. Distri bution and migration of asialoglycoprotein receptors on the surface of a hepato cyte was followed under a scanning electron microscope using a latex probe whose surface was coated with lactose-substituted polystyrene.
