1	VAPOR DIFFUSION, SITTING DROP		293	The concentrated enzyme solution contained 6.2 mg/ml protein dissolved in 500 mM NaCl, 25 mM Tris/HCl, pH 8.5. Nine volume parts of this protein stock solution were mixed with one part 12 mM ARC-1154 dissolved in 100% dimethyl sulfoxide. The CK2alpha1-335/ARC-1154 mixture was incubated for 30 min at room temperature. The best crystals grew with a reservoir solution composed of 4.4 M NaCl, 100 mM citric acid, pH 5.25 and mixing 2 microliter of this reservoir solution with microliter CK2alpha1-335/ARC-1154 mixture, VAPOR DIFFUSION, SITTING DROP, temperature 293K
