Crystallization

Crystalization Experiments
pH 7.5
Details CRYSTALS WERE GROWN BY EQUILIBRATION OF 1 ML OF 30 MG/ML PROTEIN WITH 1 ML OF MOTHER LIQUOR (1.8 M AMMONIUM SULPHATE, 10 MM COCL[2], 100 MM MES PH 6.5) AGAINST A 1 ML RESERVOIR OF MOTHER LIQUOR. CRYSTALS APPEARED AFTER 2-3 DAYS A LARGEST DIMENSION OF 0.4 MM.
