1	VAPOR DIFFUSION, HANGING DROP	7.4	292	Crystals were grown at 19 C using the hanging drop method by mixing 2 uL of protein solution (385 uM of protein in 20 mM NaPi pH 6.5 and cellotriose 5 mM) , with 2 uL of resevoir buffer (100 mM Tris HCl pH 7.4 with 17.5 pc w/v polyethylene glycol 600) containing seeds. Crystals were cryoprotected by equilibrating 2 hours the drop against 500 uL reservoir containing 0.1M Tris PEG 600 30pc pH 7.4.
