Crystalization Experiments
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 7.0MG/ML BACE IN 10MM TRIS-HCL PH 7.4, 25MM NACL, WITH A 3-FOLD EXCESS OF INHIBITOR ADDED FROM A 50MM STOCK SOLUTION IN DMSO (2.85% DMSO IN DROP). CRYO-PROTECTANT WAS 2.5M LITHIUM SULFATE, 2.0% DMSO, 1MM INHIBITOR., VAPOR DIFFUSION, temperature 292K
