1VAPOR DIFFUSION, HANGING DROP293Protein, 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, 0.17 M ammonium citrate pH 5.6, and 20 mM L-Asn. Resulting droplets were equilibrated against the precipitant. For the data collection, crystal was mounted in a quartz capillary
