1	VAPOR DIFFUSION, HANGING DROP	7	293	Protein, at the concentration 15 mg/ml in 50 mM HEPES buffer pH 7 and 150 mM sodium chloride was mixed with equivolume solution of precipitant that contained, 17% (w/v) PEG3350 and 0.17 M ammonium citrate pH 7. Resulting droplets were equilibrated against the precipitant. Before data collection, crystal was transferred the precipitant containing L-Asn at concentration 20 mM. Subsequently, for the data collection, crystal was briefly transferred to cryo-protecting solution, which had the same composition as precipitant (with L-Asn), except concentration of PEG3350 was increased to 35 % (v/w/) and 10% (v/v), and also contained 15% of glycerol
