Inhibition concentration-response curves for globular and ribbon isomers of AuIB in 1:10 oocytes obtained with different concentrations of ACh used as an agonist. A, concentration-response curves for AuIB(globular) in 1:10 oocytes obtained with different concentrations of ACh. B, decreasing ACh concentration (3 μm) below ACh EC50 (22.6 μm) does not improve inhibition by AuIB(ribbon) in 1:10 oocytes. Inset, bar graph showing the absence of inhibition by 10 μm AuIB(ribbon) in 1:10 oocytes with 3 μm ACh used as agonist.
