1 | VAPOR DIFFUSION, SITTING DROP | 298 | 21.6 mg/ml in 20 mM Tris-HCl, pH 7.2. Equilibrate 1 ul protein and 2 ul reservoir solution over 50 ul of reservoir solution (0.1 M Succinate/Phosphate/Glycine pH 10.0 and 25% PEG 3350). Crystals were soaked in reservoir solution supplemented with 5 mM of sLec for 20 hr |
