Lectin and free glycan competition assays. Comparison between normal adherence (100%) and inhibition with lectin or glycan pre-treatment. The smaller the bar the less C. jejuni adhered in the presence of the lectin/glycan. A. ConA competition of C. jejuni adherence to Caco-2 cells; B. UEA-I competition of C. jejuni adherence to Caco-2 cells. C. Competion assays with free glycans with C. jejuni 11168 and 331 adhering to Caco-2 cells.
