Sulforhodamine B assay on MKN45, KATO-III, HT29-5F12, HT29-5M21 and LS174T cells after single agent treatment with bromelain and NAC. As assayed 72 hours post treatment, concentration-dependent inhibition of cell proliferation was observed with escalating concentrations of bromelain (left panel) and NAC (right panel). Cisplatin was used as the positive control of the experiment (small graphs a-e). Significant changes (p <0.05) are marked by asterisks.
