1	VAPOR DIFFUSION, SITTING DROP	6.8	293	The DAXX 4HB_ATRX DBM fusion protein at 26 mg/ml was crystallized under conditions of 0.1M Sodium Cacodylate, pH 6.8, 1.2 M Ammonium Sulfate and 3% 1, 5- Diaminopentane Dihydrochloride, using sitting-drop vapor-diffusion method at 293K. In this process, o.5 uL of protein was mixed with 0.5 uL of mother liquor. All the crystals were soaked in a cryoprotectant made from mother liquor supplemented with 25% glycerol before flash freezing in liquid nitrogen.
