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 XIV 6.3MG/ML IN 10MM TRIS-HCL PH 7.4, 25MM NACL, WITH A 7-FOLD EXCESS OF BMC016 ADDED FROM A 50MM STOCK SOLUTION IN DMSO (2.0% DMSO IN DROP). CRYO- PROTECTANT WAS 1.2M AMMONIUM SULFATE, 25%(V/V)GLYCEROL, 2.0% DMSO, 1MM BMC016. |
