Control of Tumors by Antigen-Specific CD8⁺ T Cells through PDL1-Targeted Delivery of Antigenic Peptide

Figure 2

Characterization of the binding of PD-L1-scFv-Fc and PD-L1-scFv-Fc-RE7 to ID8-luc tumor cells using flow cytometry. (a) Representative flow cytometry analysis of commercial antibody bound to PD-L1 (blue clear histogram) or isotype control (shaded histogram). (b) Representative flow cytometry analysis of PDL1-SCFV (green), PDL1-SCFV-RE7 (red), or isotype control (purple shaded histogram).
