1	VAPOR DIFFUSION, SITTING DROP	5.5	291	The protein was crystallized by mixing 0.45 uL of 12 mg/mL protein solution in 10 mM Hepes, pH 7.5, 50 mM NaCl, with 0.45 uL 16% (w/v) PEG3350, 0.25 M MgCl2, 0.2 M KBr, 0.1 M BisTris, pH 5.5 and 0.1 uL crystal microseeds in 26% (w/v) PEG3350, 0.25 M MgCl2, 0.2 M KBr, 0.1 M BisTris, pH 5.5. After at least 4 days of crystal growth, 40 nL of 100 mM compound, solubilized in 100% DMSO, was added using an acoustic droplet dispensing system.
