1	VAPOR DIFFUSION, HANGING DROP	9	277	Crystallization buffer: 25 mM Bis-Tris Propane pH 9, 39% PEG 200, 250 mM CsCl, 10% glycerol. After setting up the crystallization drop with the mother liquor in a 1:1 uL ratio using the liquid bridge method, 2-mercaptoethanol was added to the reservoir at a final concentration of 143 mM. Crystals were cryoprotected in the same reservoir crystallization buffer.
