The dilution factor for all dilution simulations is equal to 10. Extinction coefficients for the bound species are equal to 1. IF: (Rapid binding example from Figure 2A) kon = 100 mM−1 s−1, koff = 50 s−1, kf = 1 s−1, kr = 0.8 s−1, KD,app = 0.22 mM, KD = 0.5 mM, CS: (Rapid binding example from Figure 2D) kf = 1 s−1, kr = 0.8 s−1, kon = 100 mM−1 s−1, koff = 50 s−1, KD,app = 0.9 mM, KD = 0.5 mM.
