ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION	5.5	292	CRYSTALS WERE GROWN AT 19C BY VAPOUR DIFFUSION IN HANGING DROPS FROM 1.0M AMMONIUM SULFATE. PROTEIN STOCK WAS 8.45MG/ML BACE IN 10MM TRIS-HCL PH 7.4, 25MM NACL, WITH A 2-FOLD EXCESS OF INHIBITOR ADDED FROM A 10MM STOCK SOLUTION IN DMSO (4% DMSO IN DROP).CRYO-PROTECTANT WAS 22%(V/V) GLYCEROL, 78% (V/V) RESERVOIR SOLUTION., VAPOR DIFFUSION, temperature 292K
