1	VAPOR DIFFUSION, HANGING DROP	7	298	Crystals were grown in a Coy anaerobic chamber under an Ar/H2 gas mixture. OOR was mixed with the well solution containing PEG 3000 and Tacsimate (pH 7.0), in drops composed of 1 uL well solution and 1 uL OOR (30 mg/ml) with the addition of 0.2 uL of 100 mM oxalic acid (pH 8.0) to the crystallization drop
