From the results of the measurements of fluorescent probes MC540, DPH and acrylodan, it is suggested that the physical state change of lipid bilayer may mediate the conformation of Gs with higher activity.

• 用反映磷脂分子的堆积程度的荧光探剂MC540和脂双层的流动性变化的DPH以及专一性标记蛋白质巯基（－SH）基团的荧光探剂acrylodan的测定结果表明，不同磷脂影响Gs的活力的差异主要是由于脂质物理状态的不同所致。
