Product Specifications
Immunogen
Synthetic peptide corresponding to the junctional region of the truncated receptor LEEKKGNYVVTDHC,conjugated to keyhole limpet haemcyanin.
Specificity
Clone DH8.3 of EGF R/ErbB1 antibody is specific for Truncated EGFR which is also called EGFR type III, EGFRvIII or delta-EGFR (characterised by a deletion of 267 amino acids in the extracellular domain, leading to a receptor which is unable to bind ligand yet is constitutively active). Because of its impaired internalisation and degradation, EGFRvIII is known to enhance tumourigenesis. NOTE: Clone DH8.3 DOES NOT cross-react with full length or wildtype EGFR (wtEGFR).

Background: EGFR
In addition to its role in normal development, EGFR mutations or overexpression is observed in many tumors, including breast cancer, non-small cell lung carcinoma (NSCLC), colon cancer, and more (3-6). Small molecule tyrosine kinase inhibitors (TKIs), like gefitinib, erlotinib, and afatinib, have shown great efficacy in treating patients with EGFR activating mutations, especially for NSCLC (4-6). However, most patients eventually develop acquired resistance to TKIs and thus combination and alternative therapies are in development (4-6). A third-generation TKI, osimertinib, is approved for NSCLC patients with resistance to first-line EGFR TKI treatment (6). Additionally, combination therapies of EGFR TKIs with monoclonal antibody immunotherapies, like anti-PD-L1, are being further investigated in clinical trials (6).
