a liver plasma membrane isolation procedure has been devised which selects for the sinusoidal face of the liver parenchymal cell as assessed by marker enzyme analysis : for these plasma membranes the purification of gamma-glutamyltranspeptidase is 21.5 and the recovery is 42 % indicating that this is the cellular and subcellular locus of the enzyme in rat liver .
