ID	Method	pH	Temperature	Details
1	BATCH CRYSTALLIZATION	8.5	292	CRYSTALS WERE GROWN IN 2.5M AMMONIUM SULFATE SOLUTION, BUFFERED WITH 20MM TRIS/ HCL TO PH 8.5. THE CRYSTALLIZATION SOLUTION WAS REPLACED IN STEPS AGAINST A SOLUTION CONTAINING 2.5M AMMONIUM SULFATE, 20MM TRIS, 300MG/ML TREHALOSE AT PH 8.5., BATCH CRYSTALLIZATION, temperature 292K
