The refolding kinetics of protein L under conditions of moderate stability are well fitted as a single-exponential process over a temperature range of 37°C to −3.5°C. Correlation statistics and the mean amplitude and serial correlations of the residuals all indicate that a single-exponential model accurately fits the observed data. Stretched-exponential models (Eq. 2) neither produce statistically significant improvements in the fit nor predict heterogeneity factors, h, differing significantly from unity (Table 1).
