ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP		296	1 uL protein (21.6 mg/ml in 20 mM Tris-HCl, pH 7.2) and 2 uL reservoir solution over 50 uL of reservoir solution (0.1 M Succinate/Phosphate/Glycine pH 10.0 and 25% PEG 3350). Fully formed crystals were soaked in reservoir solution supple-mented with 5 mM Neu5Ac alpha2,3GalOMe
