The bsAb stained HER2-positive cancer cell lines, including human non-small-cell lung cancer (NSCLC) cell lines A549 and NCI-H460, human ovarian cancer cell lines SKOV-3 and A1847, and human breast cancer cell line SKBR3, but not HER2-negative Chinese hamster ovary (CHO) cells (Figure 1F) [61]. This evidence concerns the gene ERBB2 and non-small cell lung carcinoma.
