1	VAPOR DIFFUSION, SITTING DROP	5	293	Crystals were grown in a MRC SD2 plate set by a SPT Labtech Mosquito crystallization robot. 200 nL of protein at 29.5 mg/mL was mixed with 200 nL of reservoir solution, consisting of 0.1 M sodium citrate buffer, pH 5, 20% w/v PEG 6000. Vapor diffusion against 50 microliters of reservoir.
