1 | VAPOR DIFFUSION, HANGING DROP | 8 | 293 | Holo protein, concentrated to 10 mg/mL in 10 mM Tris pH 7, 100 mM NaCl, 5mM DTT, was mixed with an equal volume of 100 mM Tris pH 8, 200 mM NaCl, 23% w/v PEG 3350 and 5% v/v ethylene glycol. Suitable crystals were soaked with 2 mM 5'-O-(N-(L-seryl)-sulfamoyl)N3-methyluridine in a solution similar to the crystallization condition but containing 22% v/v ethylene glycol. |
