Figure 3. Enzyme fragment complementation (PathHunter) assay to monitor receptor/arrestin interaction.

Figure 3

(A) GLP-1 and GIP stimulated the recruitment of arrestin to their respective receptors in a dose-dependent manner. Curves represent one of three independent experiments, where each data point represents the mean of triplicates, with S.E.M displayed as error bars. (B) Comparison of maximum arrestin binding. The results are expressed as the mean ± standard error of the mean for at least 3 independent experiments; ***indicates P<0.0001.
