From: Novel HER2 Aptamer Selectively Delivers Cytotoxic Drug to HER2-positive Breast Cancer Cells in Vitro
Cytotoxicity assays of Dox and Apt-Dox. The HER2-positive SK-BR-3 cells and the HER2-negative MDA-MB-231 cells were treated with aptamer, Dox, or Apt-Dox. After 40 h of further incubation, the cells were evaluated with standard MTS assay (mean ± SD, n = 6). The star indicates a statistically significant difference between the Dox and the Apt-Dox groups (p < 0.05).
