the conductance increase is absolutely dependent on three conditions : the presence of at least 0.5 mm ca++ , an acidic phospholipid such as phosphatidylserine or diphosphatidylglycerol in the blm phospholipid mixture , and an osmotic gradient across the sr vesicle membrane , with the internal osmolarity greater than the external .
