the membranes from such pretreated cells were exposed to alkali to inactivate adenylate cyclase , and the receptors were transferred to a foreign adenylate cyclase by membrane fusion with polyethylene glycol . beta receptors from desensitized cells exhibited a reduced ability to maximally stimulate the foreign adenylate cyclase , but remained accessible to [ 3h ] cgp-12177 in the fused membranes .
