| 1 | VAPOR DIFFUSION, SITTING DROP | 8 | 291 | Protein concentrated to a final concentration of 10 mg/ml in 20mM Tris (pH8.0), 300mM NaCl. Crystals obtained by the sitting-drop vapor-diffusion method at 291K, by equilibration of drops of 0.1uL protein + 0.1uL crystallization buffer ( 0.2 M Magnesium chloride hexahydrate, 20% w/v Polyethylene glycol 3,350) against 50uL of the crystallization buffer |
