1VAPOR DIFFUSION, SITTING DROP7.5277Drop: 2 uL 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 15-17% polyethylene glycol 8000). Well: 500 uL of precipitant solution. The protein solution was prepared as follows: 0.36 uL of 100 mM of Na3VO4 and 10 uL of 50 mM of DADEYL peptide (at pH 8.5-9.0) were mixed and allowed to react for 1-1.5 hour; then, 50 uL of native PTP1B (12 mg/mL in 10 mM Tris pH 7.5, 25 mM NaCl, 0.2 mM EDTA and 3 mM DTT) was added and the solution used immediately for crystallization.
