1	hanging drop		292	CRYSTALS WERE GROWN AT 19C BY VAPOUR DIFFUSION IN HANGING DROPS USING 1.0M UNBUFFERED AMMONIUM SULFATE AS PRECIPITANT. PROTEIN STOCK WAS BACE MUT46B BATCH IX 8.1MG/ML IN 10MM TRIS-HCL PH 7.4, 25MM NACL WITH A 4-FOLD EXCESS OF BMC026 ADDED FROM A 100MM STOCK SOLUTION IN DMSO. CRYO-PROTECTANT WAS 2.0M LI2SO4, 2%(V/V) PEG 400, 0.1M CITRATE PH 5.5, 0.5MM BMC026, 1% DMSO.
