1	VAPOR DIFFUSION	7	289	0.2 ul of 12 mg/ml protein in 20 mM HEPES pH 7.5, 150 mM NaCl, 10% Glycerol, 0.1% Sodium Azide, 0.5 mM TCEP, 5 mM NADPH, and 50 mM oxalic acid pH=7.0 were mixed with 0.2 ul of the MCSG Suite 2 condition #28 (0.2M Ammonium Citrate Tribasic, anhydrous, 20%w/v PEG 3350 pH=7) and equilibrated against 1.5 M NaCl solution in 96 Well 3 drop. Before crystallization, the protein-ligand mixture was incubated with 1/15 v/v of 1 mg/ml rTEV solution at 289 K for 3 hours
