1	hanging drop		292	CRYSTALS WERE GROWN AT 19C BY VAPOUR DIFFUSION IN HANGING DROPS FROM 1.0M AMMONIUM SULFATE. PROTEIN STOCK WAS BACE MUT46B BATCH XII 8.45MG/ML IN 10MM TRIS-HCL PH 7.4, 25MM NACL, WITH A 2-FOLD EXCESS OF BMC024 ADDED FROM A 10MM STOCK SOLUTION IN DMSO (2% DMSO IN DROP). CRYO-PROTECTANT WAS 1.2M AMMONIUM SULFATE, 25% GLYCEROL, 0.4MM BMC024, 4% DMSO.
