Supplementary Figure 7: Cell surface levels of HER2 on cancer cells.

Cells were incubated on ice with 33 nM Alexa 647-labeled pertuzumab (Pertuzumab), an Alexa 647-labeled isotype control (Control IgG), or medium (Untreated) for 30 minutes, washed and analyzed by flow cytometry. Data shown is representative of three independent experiments.
