Abstract
The method of isolating plasma membranes from chick embryo chorioallantoic membranes is described along with some morphological and chemical properties of these membrane preparations. Besides 5'-nucleotidase, alkaline phosphodiesterase, alkaline phosphatase, ribonucleaseendonuclease and 2',3'-cyclic nucleotide 3'-phosphohydrolase activities, the plasma membranes possesses a high activity of 2',3'-cyclic nucleotide 2'-phosphohydrolase. They exert negligible activities for glucose 6-phosphatase and succinate dehydrogenase.
