Neutron diffraction patterns recorded at the LADI-III diffractometer at the ILL in Grenoble, France, using a large-volume TTR crystal obtained by CD. (a) The position of the crystal in the capillary is marked as a boxed area in the schematic (B = bottom; T = top). As described in Section 3.5, the fully hydrogenated (100% H) crystal was obtained from the L3 (1 mm) capillary containing 30 mg mL−1 protein with 0.15%(w/v) agarose gel and had an estimated volume of 0.7 mm3. (b) Test neutron diffraction pattern recorded from TTR crystal hydrated with natural-abundance H2O. (c) Neutron diffraction pattern recorded from the same sample following stepwise exchange of H2O by D2O. |
