Extended Data Fig. 7: Cytolysis of the CD38 trispecific Ab of CD38+ hematological cancer cell lines.

Cytolytic activity of the CD38/CD28xCD3 trispecific FALA mutant Ab against indicated CD38+CD28- lines, including acute myelocytic leukemia (AML (KG-1)), a B cell lymphoma (OCI-Ly19), acute T lymphocytic leukemia (ALL (KOPN8)), and chronic lymphocytic lymphoma (CLL(Z-138)). The representative nonlinear regression graphs (ordinary fit) ± SD are from 2 PBMC donors performed in two separate experiments.
