Crystalization Experiments
ID	Method	pH	Temperature	Details
1	MICROBATCH	7	293	CRYSTALS WERE GROWN AT 20 DEGREES, USING THE METHOD MICRO-BATCH UNDER OIL. 2.5 UL PROTEIN SOLUTION (3 MG/ML) WAS MIXED USING VORTEX WITH 1.75 OR 2 UL OF CRYSTALLIZATION SOLUTION CONTAINING 30% PEG 3350, 100 MM BIS-TRIS BUFFER PH 7 AND 1% (W/V) N-OCTYL-B-D- GLUCOSIDE AND IMMEDIATELY PLACED UNDER PARAFFIN OIL. THE DROPS WERE IMMEDIATELY STREAK SEEDED AND CRYSTALS GREW IN A FEW HOURS.
