For this purpose, we designed an antibody panel for a spectral flow cytometry analysis conceived to detect a range of immune-checkpoints (Table S6), also in relation to the bulk RNA-seq results from the Alb-R26Met tumor model (Figures 2A, 2B, and S2B), while reanalyzing again at D10 the composition of immune cell types in the tumor microenvironment. This evidence concerns the gene ALB and neoplasm.
