1	VAPOR DIFFUSION, HANGING DROP		293	Crystals of the host-guest complex were obtained in 5 mM magnesium acetate, 50 mM ADA, pH 6.5, 9% PEG4000. To obtain complexes with BLM, crystals were soaked in well solutions containing 0.1 mM BLM followed by stabilization in 9% PEG4000, 5 mM magnesium acetate, 100 mM HEPES pH 8.0, 20% ethylene glycol, 0.25 mM BLM until unit cell changes correlating with binding of BLM were detected.
