1 | VAPOR DIFFUSION, HANGING DROP | 294.15 | Crystals were obtained at 21C in dark from a 1:1 mixture of protein (10-12 mg/mL) and a reservoir solution consisting of 5% PEG 6000 and 0.1 M HEPES pH 7.1. Crystal reached maximum size after 4-5 days and were harvested at that time in the dark. Crystals were transferred to cryoprotectant solution consisting of 5% PEG 6000, 0.1 M HEPES pH 7, 2 mM DTT and either 30% P400 or 30% glycerol. Crystals were flash-frozen in liquid nitrogen in the dark |
