1 | VAPOR DIFFUSION, HANGING DROP | 277.15 | Purified protein complexes were concentrated to 7.4 mg/mL before crystallization. The crystals were grown in 12.5% PEG 4000 and 0.1 M MES (pH 6.5) via hanging drop vapor diffusion. Crystals were harvested and cryoprotected in 8% glycerol/92% mother liquor and immediately stored in liquid nitrogen |
