X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	8.4	298.0	deoxy-HbTb crystals have been grown using 8-9.5 mg/ml protein mixed with equal amount of 7-12 % w/v PEG 6000, PBS 100 mM, KCl 0.3 M, pH 8.4. Deoxy HbTb crystals were then soaked for several hours in a deoxygenated, CO saturated, stabilizing solution containing 30% w/v PEG 6000, 100 mM Trsi-HCl pH 8.4, 200 mM KCl, 5 mM dithionite reducing agent and flushed with gaseous CO before data collection, VAPOR DIFFUSION, HANGING DROP, temperature 298.0K
