Crystalization Experiments
ID	Method	pH	Temperature	Details
1	COUNTER-DIFFUSION	7.1	293	COUNTER DIFFUSION IN MICROGRAVITY CONDITIONS; COUNTER-DIFFUSION METHOD USING JAXA CRYSTALLISATION BOX (JCB). 40mm X 0.5mm CAPILLARIES WERE FILLED WITH 8.1mg/ml PROTEIN SOLUTION AND INSTALLED INTO JCB SYRINGE CASE FILLED WITH MOTHER LIQUOUR (1.7M Sodium CITRATE, 0.1M MES, 7.1). CRYSTALS WERE IN ORBIT FOR 2.5 MONTHS IN THE PROTEIN CRYSTALLISATION RESEARCH FACILITY ON THE JAPANESE EXPERIMENT MODULE OF THE INTERNATIONAL SPACE STATION., Counter Diffusion, temperature 293K
