Fig. 3From: Novel tri-specific tribodies induce strong T cell activation and anti-tumor effects in vitro and in vivoBinding affinity of parental Tb535H and novel 53X tribodies to recombinant CD3 protein by ELISA. A Binding curves by ELISA assays of tribodies (0 – 500 nM) to immobilized recombinant human CD3ε/δ heterodimer. Binding values were reported as the mean of determinations obtained in three independent experiments. B Table reporting the EC50 (nM) values for CD3 binding of each indicated tribody. Standard Deviations were ≤ 3—10%Back to article page
