| 1 | VAPOR DIFFUSION, SITTING DROP | 289 | The purified protein which contained 100 uM m7-GTP was then concentrated to about 7 mg/mL in 20 mM Hepes, pH7.6, 100 mM KCl, 1mM DTT, 0.1 mM EDTA for crystallization. The m7-GTP-bound eIF4e protein was crystallized with 1:1 ratio of protein solution to reservoir solution of 17-20% PEG-3350 and 0.1-0.4M Na formate, VAPOR DIFFUSION, SITTING DROP, temperature 289K | |
