  • Samples were incubated at 37°C overnight (16 h). Released glycans were purified using a 10 kDa molecular weight cut-off filter and reduced to dryness via vacuum centrifugation. Glycans were labeled with 2-aminobenzamide via reductive amination in the presence of sodium cyanoborohydride in 70:30 DMSO/acetic acid solution for 2 h at 65°C.
