Ludger - Biopharmaceutical Glycoprofiling

HPLC Analysis of Fluorescently labelled N-Glycans To enable the detection following separation of N-glycans by HPLC, the glycans are flourescently labelled with aryl amine compounds by reductive amination. The most commonly used flourescent label is 2-aminobenzamide (2AB), although 2-aminobenzoic acid (2-AA) and 2-aminopyride (2AP) are also used. The labelled glycans can then be analysed by a range of HPLC methods.
