Fig. 4. Flow cytometric analysis of the effects of ERC6-complexed Cot-Biotin-Cot on an EGFR-positive lung adenocarcinoma cell line.

A549 cells were incubated with cetuximab, anti-cotinine IgG, ERC6, or negative control IgG (Neg. control IgG) in the absence (w) or presence (w) of Cot-Biotin-Cot peptide. The cells were probed with PE-conjugated streptavidin and FITC-conjugated anti-human Fc for analysis. PE phycoerythrin, FITC fluorescein isothiocyanate
