Supplementary Figure 4: Gating strategy for live fluorescence barcoding of T cell clones

Shown is an example with four live fluorescent dyes. Cell were labelled with 9 combinations of three distinct dilution of Violet and Far red dyes. Cells with each of the nine cluster were labelled with 6 combinations of 4 distinct dilutions of CFSE and and 3 of CMTMR orange dyes. Dilutions used for adjacent clusters across the 640-670 axis were labelled with alternate dilutions of CFSE and CMTMR Orange (as shown in the overlaid plots) in order to reduce spill-over in case of suboptimal separation between clusters across the channel-dye combination with the lowest stain index.
