1MICROBATCH6.3291MICROBATCH METHOD UNDER OIL WAS USED. 15.1 MG/ML OF PROTEIN SOLUTION CONTAINING 0.02M DTT WAS MIXED WITH 1.65M SODIUM ACETATE AND 0.1M MES PH 6.3. THE CRYSTALLIZATION TEMPERATURE WAS 291 K. PARATONE-N OIL MIXED WITH 10% W/W OF GLYCEROL WAS USED FOR CRYOPROTECTION. LIGAND BOUND CRYSTALS WERE OBTAINED BY 7 H SOAKING OF NATIVE CRYSTALS IN SOLUTION CONTAINING 1.2M SODIUM ACETATE PH 6.3, 20MM AMMONIUM SULFATE, 2MM MAGNESIUM SULFATE AND 5MM ADENOSINE
