Fig 12. RP-UPLC analysis of sialic acids.

Fig 12

(A-F) Polysaccharides were acid hydrolyzed and liberated sialic acids were derivatized with DMB for fluorescence detection following separation by RP-UPLC. (G) RP-UPLC of sialic acid monosaccharide standards (5 pmole). (H) The abundance of selected monosaccharides in each sample was determined based on the standards. Abbreviations: KDN; ketodeoxynonulonic acid; KDO, 3-deoxy-D-manno-octulosonic acid; Neu5Ac, N-acetylneuraminic acid; Neu5Gc, N-glycolylneuraminic acid.
