Analysis of ligand binding by monitoring changes in intrinsic tryptophan fluorescence in the presence of all-trans-retinal. Data obtained from the fluorescence emission spectra of wild type and mutant ECD2 polypeptides described in Fig. 7 were analyzed in terms of percent change in intensity versus log of the all-trans-retinal concentration.
