hEGFRvIII:CD3 bi-scFv binds only human CD3-expressing cells. (A) hEGFRvIII:CD3 bi-scFv binding to PBMCs from human, cynomolgus, beagle, mouse, pig, rabbit, and rat were tested using flow cytometry. Binding studies using only the secondary detection PEPvIII multimer served as control. (B) hEGFRvIII:CD3 bi-scFv binding to PBMCs from three human donors. Dashed line shows EC20. EC20, 20% of the maximal effective concentration; EGFRvIII, epidermal growth factor receptor variant III; PBMCs, peripheral blood mononuclear cells.
