Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	6	293	Hanging droplets were made by mixing 1.5-3.0ml of protein/inhibitor solution with 5ml of PEG solution (10% PEG6000, 0.2M Mes-NaOH, 0.02% NaN3, pH6.0). Droplets were concentrated against a reservoir buffer containing 1.0-2.0M sodium phosphate, 0.02% NaN3, pH6.0, VAPOR DIFFUSION, HANGING DROP, temperature 293K
