FIGURE 3.

Temperature dependence of the relative populations of the native, N, dimeric intermediate, I₂, and unfolded, U, states of spc-SH3 for different protein concentrations according to the model described in the text. The curves have been calculated using the parameters of Table 2 for data set A. Protein concentrations are as follows: 0.03 mM (solid line); 0.15 mM (dashed line); 0.76 mM (dotted line); 2.2 mM (dash-dot line); and 4.9 mM (dash-dot-dot line).
