Abstract: Supplemental Figure S8. In vitro characterization of all MB49 STING KO clones. A-D) MB49WT (WT) or MB49STING KO (STING KO) cells were plated (5.0 × 105 - 1.0 × 106 cells/well) and treated with DMXAA (30 μg/mL) or VAX014 (MOI 300) ± Amx (100 μg/mL) for ∼20 hours. A) IFN-β in supernatants of treated cells as measured via ELISA (n = 3–6). B) Ratio of pIRF3 to IRF3 in cells 4 hours post-treatment analyzed via Western blot. Histogram includes values from two independent experiments. C) Representative Western blot for data in B). D) Surface expression of PD-L1 and MHC-I in cells as determined by flow cytometry (n = 3). Histograms depict mean ± SEM of all combined experiments and dashed lines represent the baseline expression value of the corresponding untreated control. #indicates which STING KO clone is represented in Figure 3.
