ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	5.8	298	RESERVOIR SOLUTION: 15% PEG3350, 100MM BIS-TRIS PH 5.8, 320MM AMMONIUM SULFATE. PROTEIN SOLUTION: 20 MG/ML IN 25 MM TRIS PH 8.0, 200MM NACL, 1MM TCEP, 1MM PJ34. EQUAL VOLUMES (2 UL) OF RESERVIOR SOLUTION AND PROTEIN SOLUTION WERE MIXED AND SET AS HANGING DROPS. CRYSTALS WERE THEN MOVED INTO A SOAKING SOLUTION CONTAINING 18% PEG 3350, 320MM AMMONIUM SULFATE, 100MM BIS-TRIS, 0.2 MM INHIBITOR, VAPOR DIFFUSION, HANGING DROP, temperature 298K
