Method	pH	Temprature	Details
X-RAY DIFFRACTION	5.5	293	Crystals of the 3-OST-1/PAP/heptasaccharide complex were obtained using micro-batch technique, by mixing 1.5 mL of the complex (12.9 mg/mL 3-OST-1, 5 mM heptasaccharide, 4 mM PAP, 23.6 mM Tris pH 7.5, 142 mM NaCl) was mixed with 2.5 mL of 0.1 M sodium citrate pH 5.5 and 20% PEG 3000. Crystals grew to a usable size after 10 days incubation at room temperature. The crystals were transferred in two steps to a cryoprotectant solution containing 0.1 M sodium citrate pH 5.5, 0.1 M NaCl, 4 mM PAP, 20 mM heptasaccharide, 30% PEG3000, and 7.6% ethylene glycol. , temperature 293K
