Supplementary Table S3 for corresponding IC 50 , 95% CI for IC 50 , and efficacy (span in Y-axis). The data from three independent experiments were expressed as the mean ± SEM of duplicate treatments. The amivantamab analogue served as a positive control molecule while the null mAb served as a negative control. The abbreviations were: gMFI, geometric mean fluorescent intensity; AF647, Alexa Fluor 647 dye; AF488, Alexa Fluor 488 dye; Ab, antibody; nM, nanomolar; EGF, epidermal growth factor; HGF, hepatocyte growth factor; SEM, standard error of the mean.
