Abstract
A method was developed for the analytical and preparative isolation of basolateral plasma membranes from rat small intestine. They were separated on a self-orientating Percoll (modified colloidal silica) gradient starting with a heavy microsomal-membrane fraction and involving centrifugation at 48,000 g for 1 h. (Na+ + K+)-stimulated ATPase activity, used as a marker enzyme for the basolateral plasma membrane, is enriched 20-fold compared with that found in the homogenate of isolated intestinal epithelial cells.Entities:
