Structural analyses of various glycans attached to proteins and peptides are highly desirable for elucidating their biological roles. An approach based on mass spectrometry (MS) combining both(More)
The intensities of ion signals from neutral oligosaccharides (N-glycans) derivatized with 2-aminopyridine (PA) were analyzed by ion trap mass spectrometry with a sonic-spray ionization (SSI) source,(More)
