X-RAY DIFFRACTION

Crystallization Details
Method pH Temprature Details
X-RAY DIFFRACTION 8.0 291 100 mM Tricine/NaOH, pH 8.0, 30% (v/v) pentaerythritol propoxylate 426 (5/4 PO/OH), and 400 mM KCl. The crystallized sample has to be perfectly anoxic and extremely fresh (crystallization after 3 days of purification) without any freezing step. The optimal protein concentration is 30 mg/ml. Drops are made by mixing 1 ul of protein and 1 ul of precipitant. Crystals appeared usually after 7-10 days anoxically.
