Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP		295	Protein concentration : 10 mg.ml-1 Crystallization drop : 1.5 ul of protein and 1.5 ul of the precipitant. Crystallization solution : 2.8 to 3.4 Sodium malonate pH 5.5. Note : Tb-Xo4 was solubilized with the protein solution for a final concentration of 10 mM, 1 hour before to perform the crystallization drop.
