Equilibrium unfolding (bRf-to-bOu) and refolding (bOu-to-bRf) of wild-type protein. (a) The unfolding and refolding samples without added RET monitored by absrobance at 560 nm after incubated for ~9 days. (b) The unfolding and refolding samples without added RET monitored by fluorescence at 335 nm after incubated for ~9 days. (c) The unfolding and refolding samples with added RET monitored by absrobance at 560 nm after incubated for ~4 days. (d) The unfolding and refolding samples with added RET monitored by fluorescence at 335 nm after incubation for ~4 days.
