1 | VAPOR DIFFUSION, HANGING DROP | 290 | Drop Contained: 2 uL 40 mg/mL protein, 2 uL reservoir solution (16% PEG 3350, 450 mM lithium citrate and 10 mM magnesium chloride) and 0.5 uL 1:10^3 dilution of seed stock prepared according to the Seed Bead protocol. Crystals were transferred to a drop containing 35% PEG 3350, 166 mM lithium citrate, 166 mM magnesium chloride, 10% ethylene glycol and 50 mM trehalose for 30 minutes prior to cryocooling. |
