Le<sup>X</sup> blocks binding of CTB to human granulocytes but not murine leukocytes.

<p><b>(A-B and D-E)</b> Histograms from flow cytometry analyses of CTB-, G33D- and OVA-binding to granulocytes in human peripheral blood. CTB was pretreated or not with titrated amounts of <b>(A)</b> Le<sup>X</sup>-os, <b>(B)</b> GM1-os, <b>(D)</b> os-HSA (not titrated) and <b>(E)</b> Le<sup>X</sup>-os and GM1-os. Graphs show the percent of gMFI of CTB binding to the cells where 100% represents CTB staining with no blocking oligosaccharide. <b>(C)</b> Histograms from flow cytometry analyses of CTB-, G33D- and OVA-binding to CD3+ T cells gated from murine splenocytes. CTB was pretreated or not with the indicated os or os-HSA. <b>(A-B)</b> n = 3, <b>(C)</b> One representative out of three independent experiments, <b>(D)</b> n = 8, <b>(E)</b> n = 4–9. Error bars show SD. Each dot represents one donor and significance was calculated using a one-way-ANOVA with Tukey correction compared to CTB without block if not indicated otherwise with bars (**** = p<0,0001, *** = p<0,005, ** = p<0,01).</p>
