Background |
Epidermal growth factor receptor variant III (EGFRvIII) is the most common EGFR mutation, present in up to 30% of high-grade gliomas, particularly glioblastoma multiforme (GBM). EGFRvIII is a cancer-specific deletion mutant, restrictively expressed in glioblastoma and some lung cancers, and is not detected in normal tissues. EGFRvIII plays a critical role in tumorigenesis, disease progression, and metastasis, and is recognized as a cancer driver mutation in glioblastoma. Its expression is associated with poor prognosis, making EGFRvIII an ideal target for immunotherapy.

Quality Control |
Fig. A: Flow cytometry assay demonstrating cell binding specificity. U87 cells (EGFRvIII negative), U87 (EGFR++), and U87 (EGFRvIII++) cells were stained with 5 µg antibody in 1 mL PBS containing 5% BSA. Binding was detected with a Cy5-conjugated goat anti-rabbit antibody. Shaded area: isotype control; red line: EGFRvIII antibody staining.
Fig. B: ELISA assay demonstrating target specificity. Recombinant EGFR-hFc (negative control), EGFRvIII-hFc (target), and BSA were immobilized at 5 µg/mL. Biotinylated antibody (1:2 serial dilutions from 200 nM) was incubated at 37 °C for 30 min. Binding was visualized with HRP-conjugated streptavidin.
