Cell viability in the presence of live L. reuteri Protectis bacteria. Different concentrations of L. reuteri Protectis bacteria were added to RD cells (a) and Caco-2 cells (b) and incubated for 1 h, then washed with PBS thrice before 50 μg/ml gentamicin-supplemented maintenance media was added to the cells. Alamar blue assay was performed at 24 h post-treatment according to the manufacturer’s instructions. Data are expressed as the mean ± standard deviation of technical triplicates. Two biological repeats were conducted. One representative is shown
