| 1 | VAPOR DIFFUSION, HANGING DROP | 7.25 | 293.15 | F-BARx-WT was eluted from the anion exchange column (MonoQ-GL10/100, GE Healthcare) in buffer containing 5% Glycerol, 25 mM Tris buffer pH=7.4, 5 mM ?-mercaptoethanol, and ~0.16 M NaCl at the elution peak and concentrated to 18 mg/ml. F-BARx-WT crystals grew in 0.2 M ammonium citrate tribasic pH=7.25, 35% PEG1500. |
