Generation and binding of human CLEC9A-NY-ESO-1, DEC-205-NY-ESO-1 and control-NY-ESO-1 chimeric Ab. (A) Diagram of chimeric Ab consisting of rat or mouse variable regions specific for human CLEC9A, DEC-205, or β-galactosidase (control), and human IgG4 κ constant regions genetically fused to an antigenic sequence of NY-ESO-1. (B) Binding of CLEC9A-NY-ESO-1 (blue, left panel), DEC-205 (red, right panel) to 293 F cells transfected with CLEC9A (left) or DEC-205 (right) and untransfected controls (gray). (C) Binding of chimeric Abs to human Ag presenting cells, shown as representative histograms from one donor and the median fluorescence intensity±SD compiled from five individual healthy donors. Ab, antibody; Ag, antigen; MFI, median fluorescence intensity; NY-ESO-1, New York esophageal squamous cell carcinoma 1.
