Flow cytometry analysis showing calcein fluorescence intensity inside SKBR3 cells incubated with the either the control or TRA-liposomes with or without prior incubation with free Trastuzumab (1 mg/ml). An average of 1 × 104 cells was analyzed from each sample with calcein fluorescence intensity showing on a four-decade log scale.
