836 A novel glycolytic enzyme-based fluorescent probe identifies functionally superior CD8+ tumor-infiltrating lymphocytes (TILs) across states of exhaustion

836 Figure 1 REPO strongly stains metabolically active acute effector CD8+ T cells derived from vaccination and weakly stains quiescent nave T cells, while murine melanoma-derived CD8+ TILs contain both REPOhi and REPOlo populations.(A) Representative plots demonstrating REPO staining intensity for CD8+ Nave T cells, CD8+ Day 5 Vaccine-Derived Effector T cells, and CD8+ TIL from murine melanomas.(B)REPOhi and REPOlo TILs are sorted by REPO intensity and stained intracellularly
