Approximate theoretical FRET efficiency curves for reduced donor–acceptor transverse distance β _w = 0.375 and reduced exclusion distance β ₁ = 1.25 (relative enrichment factor B, from bottom to top: B = 1.05, B = 1.25, B = 1.5, B = 2, B = 3; see original paper for approximation details) and experimental results of FRET between AChR tryptophan and trans-parinaric acid in egg-PC/DMPA/cholesterol (2:1:1) vesicles (Poveda et al. 2002). The best fit is obtained for B = 1.25. Reprinted with permission from Capeta et al. (2006); copyright 2006, Springer
