1	VAPOR DIFFUSION, HANGING DROP	5	290	15 mg/ml, crystallization buffer: 33% PEG 300, 0.1 M sodium citrate pH 5.0, 13% ethylene glycol (EG) and 10 mM CoCl2. For cryoprotection, the concentration of EG was slowly increased to 25% by adding a concentrated solution directly to the crystal drop. Crystals were harvested using CryoLoops (Hampton Research), looped through LV CryoOil (MiTeGen), frozen in liquid nitrogen, VAPOR DIFFUSION, HANGING DROP, temperature 290K
