Crystalization Experiments
ID	Method	pH	Temperature	Details
1	SMALL TUBES	9	293	Solution of MB (carbonmonoxy-form) (20mg/ml protein in 0.02M TRIS-HCl pH 9.0) mixed with mother liquor (3.2M ammonium sulphate, 0.05M TRIS-HCl, pH 9.0) for final concentrations of 2.5M ammonium sulphate to obtain crystals of MBCO. MBCO crystals were oxidyzed by excess of potassium ferricyanide, washed in mother liquor and reduced under anaerobic conditions with sodium dithionite, SMALL TUBES, temperature 293K
