Figure 5From: Analysis of the anti-tumor effect of cetuximab using protein kinetics and mouse xenograft modelsImmunohistochemistry of xenograft tumors. HT29 mouse xenograft tumors were removed and stained after cetuximab treatment. Tumor sections were stained with HE, anti-EGFR, anti-pEGFR(1045), anti-pERK(Thr202/Tyr204). Images are from cetuximab-treated (top) and -untreated (bottom).Back to article page
