Dynamics of Proteins by Thermal Decay of Free Radicals Induced by Ultraviolet Irradiation

Figure 4

Difference EPR spectra of free radicals induced by UV irradiation of fibroin in weakly (77–250 K) and strongly water-coupled region (250–450). (a) A: water (77 K–220 K) and B: dry (77 K–250 K) forms. (b) A: fibroin in water (280 K–290 K) and B: dry fibroin (380 K–400 K).
