X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	9.0	?	PROTEIN WAS CRYSTALLIZED FROM 3.6 M AMMONIUM SULFATE. CRYSTALS WER SOAKED FOR 1 HOUR IN A THOROUGHLY DEGASSED AND N2 - SATURATED CRYOPROTECTANT SOLUTION MADE BY ADDITION OF 100 MG SUCROSE, 100 MG GLUCOSE AND 8 MG NA-DITHIONATE TO 1 ML OF 70% SATURATED AMMONIUM SULFATE WITH 50 MM TRIS. HCL PH 9.0. THEN THE SOLUTION WAS EXCHANGED AGAINST A CO SATURATED ONE. DISTINCT COLOR CHANGES ACCOMPANIED THE FORMATION OF UNLIGATED MYOGLOBIN FROM MET-MB AND MBCO FROM UNLIGATED MB.
