Experimental details: Immunohistochemical analysis of CD45 was performed using formalin-fixed paraffin-embedded human tonsil tissue sections. To expose the target protein, heat-induced epitope retrieval was performed on de-paraffinized sections using eBioscience™ IHC Antigen Retrieval Solution - High pH (10X) (Product # 00-4956-58) diluted to 1X solution in water in a microwave at 100 degree Celsius for 10 minutes. Following antigen retrieval, the sections were blocked with 2% normal goat serum in 1X PBS for 45 minutes at room temperature and then probed with or without CD45 Monoclonal Antibody (2D1), FITC, eBioscience™ (Product # 11-9459-42) at 1:100 dilution in 0.1% normal goat serum overnight at 4 degree Celsius in a humidified chamber. ReadyProbes™ Tissue Autofluorescence Quenching Kit (Product # R37630) was used to quench autofluorescence from the tissues. Nuclei were stained with DAPI (Product # D1306) and the sections were mounted using ProLong™ Glass Antifade Mountant (Product # P36984). The images were captured on EVOS™ M7000 Imaging System (Product # AMF7000) at 20X magnification and deconvoluted externally.

Experimental details: Fig. 2 In silico validation of the immune cell scoring method. a In silico validation of immune cell scores using simulated mixing proportions. RNA-Seq profiles of FACS-sorted NK cells, macrophages, CD 4 + and CD 8 + T cells, and non-immune CD 45 - cells were mixed with known proportions to obtain a ""clean"" mixture. Noise was added at varying SNRs. Mixing levels were then inferred by ssGSEA from the ""clean"" and noisy mixtures. The Spearman correlations between the simulated and inferred levels ( top panel ) and the bootstrap p values for these correlation values ( bottom panel ) are shown on the y-axes (Additional file 1 : Figure S18 and "" Methods "" for the calculation of the bootstrap p values). b Validation of IIS with methylation-based leukocyte fractions. Spearman correlations between the two orthogonal scores are shown on the x-axis for 13 tumor types. c Validation of TIS with TCR beta chain abundance. Both scores are computationally inferred from RNA-Seq data but employ different approaches to measure T cell levels. Spearman correlations are shown on the x-axis for 19 tumor types
