We have described a method using differential centrifugation and free-flow electrophoresis for the isolation of basolateral membranes from rat renal cortical tissue. Purity of the membrane preparation was assessed by determination of enzymic constituents and substantiated by observation of transport characteristics for d-and l-glucose, l-proline and l-glutamine. Specific activity of (Na++ K+)-ATPase in the pooled electrophoretic fractions was 15.4 times that in the cortical homogenate, and the relative purification of (Na++ K+)-ATPase compared to alkaline phosphatase was 25-fold. l-Glucose showed no Na+-gradient dependence and was used as a measure of diffusion. Uptake of d-glucose as well as l-proline followed the same time course in the presence or absence of an Na+ gradient. Only with l-glutamine was uptake stimulated by the presence of an Na+ gradient. Our data indicate we have sucessfully isolated basolateral membranes which are free of brush border contamination in superior yield and with greater facility than previously reported.
