1	VAPOR DIFFUSION, HANGING DROP		277.15	Purified GsSGD proteins at a concentration of 8 mg/mL and vincosamide were combined with an equal volume of reservoir solution containing 0.13 M lithium sulfate, 0.1 M sodium citrate tribasic dihydrate and 20% PEG1000 at pH of 5.8.The crystal crystallization conditions were optimized under this condition using the Additive Screen kit (Salt: 30% v/v methanol; Classification: organic, volatile; Suggested drop concentration: 3.0%) Diffraction-quality crystals were produced within a time-frame of 14 days.
