One microgram of glycopeptides was separated on an EASY-nLC™ 1200 instrument (Thermo Fisher Scientific, Germany) with the use of Acclaim PepMap100 precolumn (2 cm, 75 µm i.d., 3 µm) and Acclaim PepMap100 separating column (50 cm, 75 µm i.d., 3 µm) operating at 300 nL/min. The mobile phase A (0.1% FA) and mobile phase B (0.1% FA / 80% ACN) with a flow rate of 200 nL/min. The parameters used for intact glycopeptides analysis were the same as previously described [22 (link), 23 (link)].
