Inhibition of Grb2 recruitment to the EGFR by EGFR-activity modulating drugs.

<p>Grb2 contrast increase upon EGF stimulation (170 nM, 15 min) in cells pre-incubated with the indicated EGFR antagonists for 4 hours in comparison to untreated cells. Error bars are based on the standard error of the mean (n = 40 cells).
