1VAPOR DIFFUSION, SITTING DROP6.5293Protein was dissolved at 4.89 mg/mL in a buffer containing 10 mM HEPES pH 7.5, 100 mM NaCl, 0.3 mM TCEP. 200 nL of protein was mixed with 200 nL of reservoir in a SD2 plate. The reservoir consisted of 21% w/v PEG 3350, 0.25 M NaCl, and 0.1 M bistris pH 6.5. Crystals were cryopreserved in 35% PEG 3350, 0.2 M NaCl and 0.1 M bistris buffer, pH 6.5.
