1	VAPOR DIFFUSION, HANGING DROP		277.15	Crystals of apo-LBD was obtained at 4 degrees Celsius by hanging drop vapor diffusion. The droplets consisted of a 1:1 (v/v) mixture of LBD at 6 mg/ml, and the well solution consisted of 100 mM sodium citrate (pH 4.6), 22% glycerol and 5% PEG4000. Crystals appeared after 24-48 h and were ready for data collection in 7 d.
