ID	Method	pH	Temperature	Details
1	hanging drop	5.6	292	CRYSTALS WERE GROWN AT 19C BY VAPOUR DIFFUSION IN HANGING DROPS USING 1.0M AMMONIUM PHOSPHATE, 0.1M NA CITRATE PH 5.6 AS PRECIPITANT. PROTEIN STOCK WAS BACE MUT46B BATCH X 8.3MG/ML IN 10MM TRIS-HCL PH 7. 25MM NACL, WITH A 4-FOLD EXCESS OF BMC001 ADDED FROM A 50MM STOCK SOLUTION IN DMSO (1.4% DMSO IN DROP). CRYO-PROTECTANT WAS 20% (V/V) 1,2-PROPANEDIOL, 80% RESERVOIR SOLUTION.
