Fig. 4. Cell line-dependent EGFR expression on HNSCC cell lines does not determine ADCC.
Cell surface levels of EGFR as mean fluorescence intensity (ΔMFI) (a) and percentage positivity (overton) (b) were correlated with fraction ADCC under normoxia (closed; ●) and hypoxia (open; ○). Correlation coefficients and significance were determined through Spearman's rank-order correlation together with the best fit curve. Points represent the mean of each cell line.
