ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	8	277	LACV-L in complex with pre-annealed 3 prime (1-16) and 5 prime (9-16) vRNA was concentrated to 5 mg/ml. The 5 prime (1-10) vRNA end was later soaked into crystals in 1 to 2 molar ratio. Mother liquor was 100 mM Tris pH 8.0, 100 mM NaCl, and 8% PEG 4000. Crystals were soaked in a stepwise manner with increasing concentration of the glycerol cryo-protectant, reaching 30%
