Summary of glycomers observed in F₁H_nN₂ series

Molecular ions represent singly charged monosodiated permethylated N-glycans in the F₁H_nN₂ series observed in MALDI-TOF MS spectra (Fig. 1). Based on the extensions seen in the core chitobioses, different glycomers were grouped into forms ranging from a-form to f-form. Percentages represent relative distributions of each glycomer observed in the MALDI-TOF/TOF MS spectra (Fig. 2). The relative distribution of each glycomer was determined by calculating the intensities of major B- and Y-ion pairs corresponding to a particular glycoform and dividing it by the sum total of the intensities of all major Band Y-ions corresponding to each glycomer within the individual parent mass.
