The resin was washed by 20 column volumes of wash buffer A [20 mM HEPES pH 7.5, 500 mM NaCl, 2% (w/v) glycerol, 0.05% (w/v) DDM, 0.01% (w/v) CHS and 30 mM imidazole] and 10 column volumes of wash buffer B [20 mM HEPES, pH 7.5, 500 mM NaCl, 2% (w/v) glycerol, 0.02% (w/v) DDM, 0.01% (w/v) CHS and 50 mM imidazole], followed by incubation with Fab7F38 at a molar ratio of 1: 1.5 in 3 mL wash buffer C [20 mM HEPES pH 7.5, 500 mM NaCl, 2% (w/v) glycerol, 0.01% (w/v) DDM, 0.01% (w/v) CHS and 20 mM imidazole] for 3 h at 4 C
The research-grade standard is lyophilized powder stored at 20C until reconstitution, then refrigerated at 28C and used within 28 days
Semaglutide mean weight change was -15.8%
