Product Description
The 2G11-2A05-CP214 monoclonal antibody is a recombinant, chimeric version of the original 2G11-2A05 antibody. The variable domain sequences are identical but the constant region sequences have been switched from Rat IgG2a, κ to mouse IgG2a, κ for use in murine models. Additionally, the constant region includes the Fc silencing mutation variant LALA-PG, rendering it unable to bind endogenous murine Fcγ receptors or C1q to induce antibody-dependent cell-mediated cytotoxicity (ADCC) or complement-dependent cytotoxicity (CDC). This allows for pure VEGF-a blockade without FcγR or complement mediated effector functions so the biological readout reflects neutralization rather than immune cell depletion or Fc‑dependent inflammation. Fc-silent antibodies can also improve in-vitro assays by reducing non-specific signaling and background. The LALA-PG variant has demonstrated significantly reduced effector function, C1q binding and C3 fixation compared to other common silencing mutations while retaining favorable biophysical and manufacturing properties and preserving FcRn-mediated half-life. The highly controlled sequence and lack of genetic drift in recombinant antibodies provide more reliable and reproducible results over hybridoma derived antibodies. Species-matched antibodies result in less immunogenicity and formation of anti-drug antibodies (ADAs) than xenogenic antibodies in animal models. The highly controlled sequence and lack of genetic drift in recombinant antibodies provide more reliable and reproducible results over hybridoma derived antibodies.
The 2G11-2A05-CP214 monoclonal antibody reacts with mouse VEGF-A (vascular endothelial growth factor A). VEGF-A is a 45 kDa homodimeric, disulfide-linked glycoprotein that plays key roles in angiogenesis, vasculogenesis, and endothelial cell growth. It promotes mitogenesis, chemotaxis, and vascular permeability. Most tumors have a requirement for angiogenesis, and inhibition of VEGF binding to VEGF receptors has been the focus of several tumor therapeutic strategies. The 2G11-2A05 antibody neutralizes the biological activity of VEGF-A.
