eng	CZE/LIF - A Powerful Tool for the Analysis of N-linked Glycans Released from Human Glycoproteins	In present work, capillary zone electrophoresis (CZE) coupled with LIF detector as a powerful tool for identification of N-linked glycan structures derived from glycoproteins is demonstrated. Complex mixtures of derivatized N-glycans were resolved on a polyacrylamide coated capillary with reduced electroosmotic flow. To detect N-glycans using high sensitive LIF detection, a highly fluorescent dye 1-aminopyrene-3,6,8-trisulfonate (APTS) as a derivatization reagent was attached to the reducing end of oligosaccharide molecule through reductive amination. Glycan structure identification was elucidated using a combination of strategies, including comparison with standard glycan libraries and the enzymatic digestions of N-linked glycan pools using specific and non-specific exoglycosidases.
