| 1 | VAPOR DIFFUSION | 7 | 291 | 20% PEG 6000, 0.2 M MgCl2, and 0.1 M HEPES pH 7.0, by mixing 1 uL of protein with 0.5 uL of mother liquor. Crystals were transferred to a soaking solution containing mother liquor and 66 mM fructosyl-erythritol for 4 hours, and subsequently to a fresh drop supplemented with 25% ethylene glycol . |
