ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP		293	The purified protein which contained 100 uM m7-GTP was concentrated to about 7 mg/mL in 20 mM Hepes, pH 7.6, 100 mM KCl, 1mM DTT, and 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 293K
