Inhibition of ErbB3-driven proliferation of cancer cells. (a) The antiproliferative action of BCD090-P1 or BCD090-M2 on MCF-7 cells, rituximab and HeLa cells expressing negligible amounts of ErbB3 were used as negative controls; (b) the growth curves of MCF-7 cells treated with 50 μg/mL single-domain antibodies; (c) antiproliferative action of BCD090-P1, BCD090-M2 or trastuzumab on SK-BR-3 cells; (d) the viability of SK-BR-3 cells treated with a mixture of the two single-domain antibodies. The dose–response curves were fitted by the Hill equation. All data represent the mean of three replicates ± SD, p-values were calculated using t-test.
