1	VAPOR DIFFUSION, SITTING DROP	8	277	Crystals were grown with the sitting-drop vapor diffusion technique by mixing 0.75 ul of the TlpA-ScoI complex (10 mg/ml in 10 mM Tris-HCl, pH 8) with 0.75 ul of precipitant solution (final concentration: 3% glycerol, 0.2 M NaSCN and 16.0% (w/v) PEG 3350) and equilibration over 100 ul of well solution (3% Glycerol, 0.2 M NaSCN, 28% PEG 3350).
