Basolateral membrane vesicles were isolated from the rat kidney cortex by a modified method of cation precipitation. Different steps of preparation were analysed using the marker enzymes: Na+,K+-ATPase (for basolateral membrane), alkaline phosphatase (for apical membrane), glucose-6-phosphatase (for membranes of endoplasmic reticulum) and succinate dehydrogenase (for mitochondria). The basolateral membrane was purified by a 8-9-fold treatment with Na+,K+-ATPase, while other membrane contaminations were as low as 2% (as compared to homogenate). The transport of 3H-p-aminohippurate (3H-PAH) by basolateral membrane vesicles was measured under different experimental conditions. The 3H-PAH uptake was found to be Na-gradient dependent. The initial rate of 3H-PAH uptake in the presence of NaCl gradient (500 pM/mg X min) was higher than without the gradient (88 pM/mg X min). It is concluded that the PAH transfer across the basolateral membrane may be energized by the Na+ chemical gradient.
