title: The isolation and characterization of the plasma membrane of cultured chinese hamster ovary cells.
abstract: Plasma membranes were prepared from cultured Chinese hamster ovary cells utilizing a two-phase polymer system and were characterized by enzymatic and chemical assay, and by electron microscopy. The usual degree of purification of presumptive membrane markers such as Na+-K+ ATPase (ATP phosphohydrolase, EC 3.6.1.3) ranged from three-to eightfold. Gel electrophoresis in SDS revealed several polypeptides and two glycopeptides which were enriched in the plasma membrane fraction.
