    A9B5-Bs-5 and A9B5-Bs-7 inhibit the growth of trastuzumab-resistant HER2-positive cancer cells. (A, B) Growth inhibition in NCI-N87 (A) and BT474 cells (B) treated with bpAbs in the absence of ligands, measured by CCK-8 assay. (C, D) Growth inhibition in NCI-N87 (C) and BT474 cells (D) treated with bpAbs in the presence <t>of</t> <t>EGF</t> or <t>HRG,</t> measured by CCK-8 assay. Serum-starved cells were incubated with anti-HER2 diluted antibodies in the presence of 1 nM HRG or 5 nM EGF. Horizontal dotted line (black) represents viability of non-treated cells referenced to 100%. Data represent mean ± SD (n = 3). (E) Heat map of EC 50 values (nM) derived from CCK-8 assays showing dose-dependent inhibition by bpAbs. Source data are available in the Source Data file.
