Figure 2.
Functional characterizations of three different bispecific antibodies with FLT3 X CD3-specificity. Symbols (•, ▪, ▴) were assigned as indicated. In c–f, a Fabsc-antibody with CSPG4 X CD3 specificity (♦) was used as a negative control. In d–f, empty and filled symbols refer to the absence and presence, respectively of FLT3+ NALM-16 target cells. The binding experiment depicted in a and b was repeated once with almost identical results. In c–f, representative results from one out of three experiments with peripheral blood mononuclear cells from different healthy donors are shown.
