1hanging drop292CRYSTALS WERE GROWN AT 19C BY VAPOUR DIFFUSION IN HANGING DROPS FROM 1.0M AMMONIUM SULFATE IN WATER. PROTEIN STOCK WAS BACE MUT46B BATCH XVI 7.0MG/ML IN 10MM TRIS-HCL PH 7.4, 25MM NACL, WITH A 6-FOLD EXCESS OF BMC014 ADDED FROM A 50MM STOCK SOLUTION IN 90% DMSO-D6 (1.7% DMSO IN DROP). A SOLUTION CONTAINING 1.2M AMMONIUM SULFATE, 25% (V/V) GLYCEROL, 1.0MM BMC014 WAS USED AS CRYO-PROTECTANT.
