In our previous study, we immunized mice with EGFR-expressed glioblastoma cells or purified recombinant EGFR to produce EMab-134 clone (IgG1, kappa), which reacted with endogenous EGFR of oral cancers in flow cytometry, Western blotting, and immunohistochemistry [11]. The gene discussed is EGFR; the disease is glioblastoma.
