Toxins Treatments:

Cells were seeded in a 96-well plate at a density of 10,000 cells/well 1 d before toxin treatment. Various concentrations of LF or FP59 combined with a fixed concentration of PA (500ng/mL) were added to the wells, and cells were incubated for 6h at 37C. Cell viability was measured by MTT assay. In other toxin treatment experiments, cells were pre-treated with various concentrations of drugs, and then treated with constant concentrations of 8.3g/ml of C. difficile toxin B, 500ng/ml of P. aeruginosa Exotoxin A, or 500ng/ml of Cholera toxin for 6hours. RAW264.7 survival was measured by MTT assay. …
