1 Supplementary figure 1. Gating strategy used for FACS sorting of TIL subsets (CD3+, CD3+CD8+/-, CD3+CD8+PD-1+/-). Two representative fresh tumor samples are shown (3903 and 3998). 3903 3998 Supplementary Fig.1

2 Supplementary Fig.2 A B C D E Shannon entropy
Supplementary figure 2. Comparison of Shannon entropy in TIL subsets. (A) Shannon entropy (a measure of clonotypic diversity) is plotted for melanoma bulk TIL and sorted TIL subsets. Entropy is calculated by summing the frequency of each clone times the log (base 2) of the same frequency over all productive reads in the sample. Samples with higher entropy have a greater diversity of clonotypes while samples with lower entropy have less clonotypic diversity. Wilcoxon matched-pairs signed rank test was applied (n=10). For samples 1913 and 3922 the CD8- subset was not available. The number of non-synonymous mutations is plotted in relationship with the percentage of CD8+PD-1+ TIL (B), Shannon entropy of TIL CD8+PD-1+ (C) , Shannon entropy of bulk TIL (D) and Shannon entropy of TIL CD8+ (E) (n=9). For samples 1913 and 3922 the CD8- subset was not available and for sample 3977 the number of non-synonymous mutations was not available.
