The pre-mixed protein was then mixed in a 2:1 ratio with 250 mM Bis-Tris-Propane, pH 8.25, 20 % (w/v) PEG4000. The final drop size was 3 uL. The crystal was soaked with 5 mM succinic semialdehyde for 2 minutes and the drop was complemented with PEG200 to a final concentration of 20 % (v/v) before flash freezing the crystal in liquid nitrogen.
