1 | VAPOR DIFFUSION, SITTING DROP | 7.5 | 277 | 2uL of protein solution (12 mg/mL PTP1B F182Q in 10 mM Tris pH 7.5, 25 mM NaCl, 0.2 mM EDTA and 3 mM DTT), 0.5 uL sucrose 30% (w/v) and 3 uL of precipitant solution (0.1 M Hepes pH 7.5, 0.2 M magnesium acetate and 15-20% polyethylene glycol 8000). The well solution was 500 uL of precipitant solution. |
