摘要: Abstract 1. Hamster fibroblast plasma membranes and endoplasmic reticulum were solubilized by sodium dodecyl sulphate 2-mercaptoethanol treatment studied polyacrylamide gel electrophoresis in the presence of sulphate. The electrophoretic patterns different. amino acid compositions three major membrane protein bands determined found to differ significantly. Both contained a fast moving component low apparent molecular weight ( 2. When cells labelled with glucosamine or fucose labels 9–12 times more concentrated than homogenate. weights glycoproteins electrophoresis.
