Figure 6. Competition study between Herceptin and compound 7 on SKBR-3 cells.
The cells were cultured as described in the methods section. Images: (A) untreated SKBR-3 cells, (B) cells with 7, (C) cells incubated with unmodified Herceptin) and then 7. Treatment with Herceptin shows that the dendrimer conjugate exclusively binds to HER-2.
