The addition of G-protein and arrestin was only carried out with the Cy3/Cy5 pair. Even though arrestin did not have A great deal outcome, the addition of G-protein led for the emergence of a 2nd peak with significantly very low FRET (indicating a sizable length involving the fluorophores) which grew to become additional populated as being the efficacy with the ligands amplified. This peak probably represents the receptor certain to empty Gi. Curiously, when GDP was added, this minimal-FRET peak shifted to slightly greater FRET values, probable reflecting a complex among the µOR and GDP-loaded Gi.
