Abstract

When performing a structural analysis of N-glycans, a number of aspects should be considered. N-Glycans may be hydrolyzed from purified glycoproteins, serum glycoprotein mixtures, or delipidated membrane fractions by chemical hydrolysis using hydrazine or enzymatical hydrolysis using PNGase F.
