Seedstock was prepared by 100 uL 25% PEG1500, 0.1 M MIB pH 7.5, 5% DMSO and 4 uL seeds from plate, vortex 5 times for 5 seconds, add 12.5 uL of MPro (35 mg/mL) and incubate at 18 deg overnight. Final sample was prepared in batch mode by adding 900 uL 25% PEG1500, 0.1 M MIB pH 7.5, 5% DMSO and 100 uL seedstock and 100 uL MPro (35 mg per mL). Add seedbeads (250 uL volume in 1.5 mL Eppi) and incubate overnight at 900 rpm and 18 deg. |
