Sensitivity of Colon26 cells to rmIFN‐β and rmIFN‐γ. A, Colon26/Luc cells (5 × 103 cells/well) were co‐cultured with or without recombinant mouse (rm) IFN‐β (10 ng/mL), rmIFN‐γ (10 ng/mL), or rmIFN‐β + rmIFN‐γ (10 ng/mL each) for 3 d. The number of live Colon26/Luc cells was determined by measuring luciferase activity. B, Numbers of viable Colon26 cells after rmIFN treatments were analyzed based on quantification of NADH. P‐values were calculated using Tukey‐Kramer test (*P < .05, **P < .01)
