Prior to freezing, the well solution was mixed in an equal volume of cryoprotectant solution with a final concentration of 9% (w/v) sucrose, 2% (w/v) glucose, 8% (v/v) glycerol, and 8% (v/v) ethylene glycol. Crystals were soaked for a few seconds in the cryoprotectant before being frozen in liquid nitrogen
