Quantitative glycan analysis of transferrin incubated with B. fragilis cells

^aTransferrin was incubated with PBS, strain 638R (wt), or the Δdon mutant for 3 hours as described in the text. The amount of glycan remaining on transferrin is shown normalized to 1 g/L of transferrin and results are the average of 2 independent samples. ND=not detected.

^bThe five major glycans on transferrin are shown and were composed of the following sugars: galactose, ; N-acetylglucosamine, ; mannose, ; fucose, ; and sialic acid .

^cThe % of the total glycans linked to transferrin prior to treatment with B. fragilis.
