ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	5.8	298	EQUAL VOLUMES (2 UL) OF RESERVIOR SOLUTION AND PROTEIN SOLUTION WERE MIXED AND SET AS HANGING DROPS. 15% PEG3350, 100MM BIS-TRIS PH5.8, 310MM AMMONIUM SULFATE. PROTEIN SOLUTION: 20 MG/ML IN 25 MM TRIS PH8, 200MM NACL, 1MM TCEP, 1MM PJ34. CRYSTALS WERE THEN MOVED INTO A SOAKING SOLUTION CONTAINING 18% PEG 3350, 320MM AMMONIUM SULFATE, 100MM BIS-TRIS PH 5.8, 0.2 MM inhibitor, VAPOR DIFFUSION, HANGING DROP, temperature 298K
