Antagonism of inhibition of adenylyl cyclase activity by a representative ligand in HEK-κ cells. Reversal of the inhibitory effect of etorphine by the antagonist Win 44,441 is shown. Maximal cAMP levels were in the range of 400–1000 pmole/well. Data presented are the average from 2 or more experiments carried out in duplicate. Error bars represent standard error of the mean.
