Figure 2
(a) A typical intensity decay with (2) (low-dose region) and (3) (high-dose region) and a dose-response curve (4) fitted to the data. The total duration of the experiment is <1 s and data collected from a thaumatin crystal are shown (thaumatin 4 in Supplementary Table S1). The transition from the low-dose region is at approximately 600 kGy (∼400 ms). (b) shows data from the same crystal split into resolution bins with (2) and (3) fitted. No fit is shown for the highest resolution shell high-dose region, as the absence/short duration of a lag phase caused the fit to fail: this is discussed in the text. Rate constants for the fits are given in Table 2. |
