1 | VAPOR DIFFUSION, SITTING DROP | 7.5 | 277 | 2uL of protein solution, 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 protein solution was prepared with 15 uL of 12 mg/mL PTP1B W179F in 10 mM Tris pH 7.5, 25 mM NaCl, 0.2 mM EDTA and 3 mM DTT, and 0.5 uL of 60 mM of sodium vanadate. The well solution was 500 uL of precipitant solution., vapor diffusion, sitting drop, temperature 277K |
