Extended Data Fig. 3. Schematic diagram of LeAPS proof of concept experiments.
Packaging cells transduced with (i) SL9 presented on HLA-A2 and LeAPS-mCherry and (ii) NY-ESO-1 presented on HLA-A2 and LeAPS-GFP were mixed at either 1:100 or 1:1000 for each to represent libraries containing 100 constructs and 1,000 constructs, respectively. These mixtures were then used as packaging lines, transfected with helper plasmids to produce viruses, and used to transduce mixtures of cell tracking dye-labeled J76 cells expressing either 868 TCR or 1G4wt TCR at defined ratios.
