Method pH Temprature Details
X-RAY DIFFRACTION ? 289.15 Crystals were grown by mixing 0.5 microL 0.2 M ammonia sulphate, 0.1 M BisTRIS pH 5.5 and 25 percent PEG 3350 with 0.5 microL 18.00 mg per mL NcCAR R-domain in 50 mM MES buffer pH pH 7.0 containing 10 mM magnesium chloride, 150 mM sodium chloride and 1 mM DTT. Crystals appeared after 6-9 weeks under vapor batch conditions.
