X-RAY DIFFRACTION

Crystallization Details
Method pH Temprature Details
X-RAY DIFFRACTION 8.5 303 Crystals were grown from 1-2 mg/ml protein stock solutions at 303 K by vapor diffusion over a narrow range of equilibration solutions optimized around 100 mM Tris-HCl, pH 8.5, 200 mM KCl, 20% (v/v) ethanol. Crystals were cryo-protected by supplementing the crystallization solutions with 25% glycerol (v/v) and subsequently flash frozen with liquid nitrogen.
