Live and dead status of Caco-2 cells after exposures to CFT from CD-9689 with or without treatments with different lactobacillus CFS. After the treatments with CFS or CFTs, Caco-2 cells were trypsinized and then florescence dye, PI and AO were added. A green fluorescence (AO) indicates live cell, while a red fluorescence (PI) indicates dead cell.
