| 1 | VAPOR DIFFUSION | 293 | Protein was concentrated to 8 mg/mL in 20 mM potassium phosphate, pH 7. Crystallization conditions: 0-4% 2-propanol, 22-24% PEG 3350 in 0.1 M HEPES, pH 7.5. The Schiff-base complex was obtained by brief soaking (about 30 seconds) in saturated ligand solution prepared with crystallization solution plus 25% glycerol | |
