Transport of sulfate and phosphate in small intestine and renal proximal tubule: methods and basic properties.
1. Isolated brush border membrane vesicles, basolateral membrane vesicles, and cultured renal epithelial cells provide good material for studying transport systems. 2. The vesicle systems have been used to study the transport of labeled phosphate, sodium/phosphate cotransport, sodium/sulfate cotransport, basolateral transport of sulfate and basolateral transport of phosphate via anion exchange. 3. Cultured renal cells show sodium/phosphate cotransport and parathyroid dependent inhibition of phosphate transport.
