Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	8	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.
