Figure 4
Change in the UV–Vis absorption spectra of FcγRIIIa crystallization solution at 100 K upon exposure to X-rays. (a) shows a contour plot showing changes at all wavelengths between 200 and 750 nm, while (b) shows the change in absorbance at 240 and 593 nm. The X-ray shutter is opened at α (t = 3.40 s), the 593 nm peak reaches a maximum at β (6.50 s), the X-ray shutter is closed at γ (12.40 s) and the 100 K nitrogen stream is blocked at δ (83 s). |
