A co-crystal with lactose, grown from 12 mg/ml galectin-8N in 10 mM lactose, 10 mM Tris/HCl pH 8.0, 1 mM TCEP and 150 mM sodium chloride mixed with 25% (w/v) PEG 2000 MME) in a hanging drop, was used to soak the compound by transferring crystals in three steps to soaking drops. These were 2 uL drops with a soaking solution of 20% ethylene glycol, 25% PEG 2000 MME, 10 mM Tris pH 8, 1 mM TCEP, 50 mM NaCl, and 2 mM compound 10. The incubation times in the first two drops were about 10 min and in the third drop about 24 h. Then the crystals were transferred to a cryo solution with the same constituents and flash-frozen in liquid nitrogen. |
