ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	7	285	1 microliter of VP1 at 10 mg/ml in 25 mM Na-HEPES, pH 7.8, 100 mM NaCl mixed with 2 microliter of crystallization buffer [25 mM Na-MES, pH 6.5, 1.5% (w/v) PEG 3350] and allowing the drop to equilibrate at 12 C by hanging-drop vapor diffusion with a well solution identical in composition to the drop except for the protein. With micro-seeding, thin, plate-like crystals appeared after 1 day and grew to full size in about two weeks., pH 7.0, VAPOR DIFFUSION, HANGING DROP, temperature 285K
