1	VAPOR DIFFUSION, SITTING DROP		293.15	10 mg/ml human Sirt3-(118-399) in 20 mM Tris/HCl, pH 8.0, 150 mM NaCl, 5% (v/v) glycerol, 1 mM TCEP were incubated with 2 mM Tat-37-59 in 10% (v/v) DMSO for 60 min at 293.15 K. The complex was crystallized using the sitting-drop vapor-diffusion method at 293.15 K with 100 mM CHES, pH 9.0, 20% (w/v) PEG 8000 as reservoir solution.
