Figure 3
Rg extrapolation to zero concentration, using I′(0) as a proxy of concentration, shows that cytochrome c does not display any non-ideal behaviour over the range tested (about 6 mg ml−1), and exhibits a constant Rg, with a mean value of 1.32 ± 0.04 nm. One data point, in the upper left of the figure can be seen to exhibit an anomalously high Rg; this point is from the image at 52 min in Fig. 1, and probably contains a very small amount of impurity or aggregate. |
