1 | VAPOR DIFFUSION, HANGING DROP | 7.4 | 295 | Protein buffer: 20 mM Tris pH 7.4, 30 mM NaCl. Reservoir: 0.14 M KBr, 24% PEG 2000 MME. Hanging drop: 1.5:1.5:1.0 ul - Reservoir-Protein (8 mg/ml)-Seed stock. Cryoprotectant = 20% glycerol; Ligand soaking performed for 5-6 min in a mixture containing 20 mM glycerol-3-phosphate (pH adjusted to 7.4), mother liquor, and cryo-protectant Ligand soaking and cryoprotectant were performed simultaneously |
