| 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 Neu5Gc alpha2,3GalOMe | |
