Non-fucosylated monoclonal human IgG1 antibody against human EGFR

Anti-hEGFR-hIgG1fut features the constant region of the human IgG1 isotype and the variable region of cetuximab. Cetuximab is a chimeric human/mouse IgG1 monoclonal antibody that targets EGFR, a cell surface receptor overexpressed in many types of cancer. EGFR is activated by binding specific ligands, including epidermal growth factor and transforming growth factor-α. Activation of EGFR promotes cell proliferation and survival, as well as angiogenesis, leading to tumor growth and metastasis. Binding of cetuximab to EGFR blocks ligand-receptor binding and induces receptor internalization and subsequent degradation. Consequently, it blocks downstream pathways which regulate cell growth and angiogenesis. In addition, it induces cell death through antibody-dependent cell-mediated cytotoxicity (ADCC) [1,2]. Cetuximab has been approved by the FDA for the treatment of metastatic colorectal cancer and metastatic squamous cell carcinoma of the head and neck  [3].

Anti-hEGFR-hIgG1 is a non-fucosylated antibody. The absence of the fucose residue from the N-glycans of IgG-Fc results in dramatic enhancement of antibody-dependent cellular cytotoxicity (ADCC) without any detectable change in complement-dependent cytotoxicity (CDC) or antigen binding capability [4,5]. This antibody was generated by recombinant DNA technology. It has been produced in CHO cells that are deficient for fucosylation and purified by affinity chromatography with protein G.

Applications: Anti-hEGFR-hIgG1fut can be used with Anti-hEGFR-hIgG1 to compare the ADCC activity.


Specificity: Targets cells expressing human EGFR (Epidermal growth factor receptor)
Clonality: Monoclonal antibody
