ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP		295	Drops were comprised of 1 microliter of concentrated protein (33 mg/ml in 150 mM NaCl, 50 mM Tris-HCl, pH 8.0), 1 microliter precipitant (8% w/v polyethylene glycol 4000, sodium acetate trihydrate, pH 4.6), and 0.2 microliter 30% xylitol. The cryoprotectant was 15% glycerol in the precipitant solution. Crystals frozen in liquid nitrogen.
