ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	4.5	291	Berkeley C10: 100 mM Sodium acetate / Hydrochloric acid pH 4.5, 100 mM Ammonium phosphate dibasic, 20% (w/v) PEG 3350, 5% (v/v) 2-Propanol, KlaeA.00020.b.B1.PW39167 at 17 mg/mL. 5mM FAD soak for 4 hours. 3 of the 4 subunits have disordered FAD in the nicotinamide ring so they appear as ADP. Plate 13676 well C10 drop 1. Puck: PSL-0803, Cryo: 30% PEG3350 + 70% crystallant.
