Effect of Na₂SO₄ and GdmCl on the stability of C (K_C) and the refolding rate (k_f)

Parameters in 1 M Na2SO4 extrapolated to 0 M GdmCl*
log KC	mCGdmCl, M−1	log kf	mfGdmCl, M−1
4.38 ± 0.06	−1.47 ± 0.02	5.71 ± 0.07	−1.30 ± 0.02
Parameters extrapolated to 0 M GdmCl and 0 M Na2SO4†
log KC	mCNa2SO4, M−1	log kf	mfNa2SO4, M−1
−0.02 ± 0.11	4.34 ± 0.14	2.56 ± 0.12	3.10 ± 0.17

^*Data were obtained by fitting refolding data over 0.4–4.4 M GdmCl at fixed [Na₂SO₄] (1 M) to Eq. 1. k_f was measured in s⁻¹. 

^†Values of log K_C and log k_f at six different concentrations of Na₂SO₄ were obtained from the data in Fig. 1B (Eq. 2) and were fitted to a linear plot verseus [Na₂SO₄]. k_f was measured in s⁻¹.
