Figure 4From: Novel HER2 Aptamer Selectively Delivers Cytotoxic Drug to HER2-positive Breast Cancer Cells in VitroFlow cytometric profiles of HB5’s bindings to HER2-positive (SKBR3) or HER2-negative (MDA-MB-231 and MCF7) breast cancer cells. SKBR3 (blue lines), MDA-MB-231 (red lines), or MCF7 (black lines) cells were incubated separately with either FITC-labeled aptamer (A) or FITC-labeled random DNA (B), and analyzed by flow cytometry.Back to article page
