[Glycoproteins of liver cell membrane]

Plasmatic and mitochondrial membranes of rat liver cells were isolated by centrifugation in sucrose density gradient, enzyme analysis of the obtained fractions being performed. Membrane proteins and glycoproteins were examined using electrophoresis in polyacrylamide gel, and changes in glycoprotein composition of plasmatic and mitochondrial membranes being demonstrated. Quantities and molecular weights of the glycoproteins were estimated.
