Figure 2From: A novel transferrin receptor-targeted hybrid peptide disintegrates cancer cell membrane to induce rapid killing of cancer cells Enhancement of lytic-peptide cytotoxic activity by addition of the TfR-targeting moiety: IC50 values of TfR-lytic hybrid peptide (A) and lytic peptide alone (B) in normal and cancer cells, and the IC50 ratio of lytic/TfR-lytic hybrid peptide (C), are shown plotted against the mean fluorescence intensity (MFI) of TfR expression.Back to article page
