WebImage cytometry on tissue sections (ICS) is designed to study the microscopically defined cell population; only cancer cells are included for analysis of DNA ploidy status. DNA histograms by ICS have also been improved with better instrumentation and software that can also detect rare events with high fidelity [16-20]. ICS is performed on WebGAPDH was used as an endogenous reference. Histograms represent statistical analysis of the relative expression levels of proteins. (C) EMT-6 cells were treated with Rh4 for 24 h and analyzed mean fluorescence intensity of PD-L1 by flow cytometry. The histogram represents a statistical analysis of mean fluorescence intensity levels of PD-L1.
