Crystallization Crystalization Experiments ID Method pH Temperature Details 1 5.8 22.5% PEG 3350, 0.18 M AMMONIUM SULFATE, 0.12 M SODIUM THIOCYANATE, 0.09 M BIS-TRIS PH 5.5, 0.01 M TRIS PH 8.5 (FINAL MEASURED PH=5.82). THE PROTEIN WAS AT 2 MM (47 MG/ML), WITH 4 MM BENZYLAMINE AND 10 MM CALCIUM CHLORIDE ADDED TO STABILIZE IT. THE CRYSTALLIZATIONS WERE SET UP WITH A PHOENITO PROTOCOL (NEWMAN ET AL. 2008), WHERE A PHOENIX ROBOT (ART ROBBINS INSTRUMENTS, SUNNYSIDE, CA) WAS USED TO DISPENSE THE PROTEIN INTO AN SD2 CRYSTALLIZATION PLATE (PRE-FILLED WITH 50 ML RESERVOIR SOLUTION) AND A MOSQUITO ROBOT (TTP LABTECH, MELBOURN, UK) WAS USED TO DISPENSE THE RESERVOIR SOLUTION AND SEED STOCK OVER THE PROTEIN DROPLET.
