Drops containing 1.5 microliters 5 mg/mL protein in 20 mM HEPES were combined with 1.5 microliters well solution (85 mM ammonium acetate, 42 mM tri-sodium citrate, 12.3% PEG 4000, 7.5% glycerol, 15 mM L-cysteine, 5 mM UDP-Glc) for 1-2 weeks. Crystals were then soaked in a solution of 53% Qiagen Cryos Suite Condition #87 with 15 mM L-cys, 30% methanol, 90 mM UDP-Galp (24hrs). Crystals were then soaked in a solution of 53% Qiagen Cryos Suite Condition #87 with 15 mM L-cys, 30% methanol, 90 mM UDP-Galp plus 100 mM sodium dithionite (3 min), pH 5.6, VAPOR DIFFUSION, HANGING DROP, temperature 298K |
