Supplementary Figure S3: MALDI-TOF MS profiles of the permethylated N-linked glycans derived from SRECs after digestion with endo-β-galactosidase. Data were obtained from the 50% acetonitrile fraction and all molecular ions are present in sodiated form ([M+Na]). Insert represents low molecular weight region from the 35% acetonitrile fraction and all molecular ions are present in sodiated form ([M+Na]).
