Product Description
The 5G4.6-CP230 antibody is a chimeric version of the original 5G4.6 antibody. The variable domain sequences are identical but the constant region sequences have been switched from Armenian hamster IgG to mouse IgG2a. 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 is useful to study the effects of TL1A neutralization without FcγR/complement‑mediated cell killing, immune activation, or Fc‑driven biodistribution artifacts enabling clean mechanistic dissection. 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. Species-matched chimeric antibodies result in less immunogenicity and formation of anti-drug antibodies (ADAs) than xenogenic antibodies in animal models and the highly controlled sequence and lack of genetic drift in recombinant antibodies provide more reliable and reproducible results over hybridoma derived antibodies.
The 5G4.6 monoclonal antibody reacts with the TNF family member TL1A, also known as TNFSF15. TL1A is expressed on activated T cells, dendritic cells, monocytes and endothelial cells. TL1A expression has been shown to be induced by pro-inflammatory stimuli such as TNFα and IL-1α. In contrast to the TNFα receptors, which are expressed on essentially all cells, the receptor for TL1A, DR3 (TNFRSF25), is primarily expressed on T cells, NK cells, and NKT cells, thereby limiting the effects of TL1A. TL1A-DR3 interactions are thought to promote effector T cell proliferation at the site of inflammation and in draining lymph nodes. Blockade of TL1A-DR3 interactions strikingly reduces pathology in several animal models in which autoreactive T cells play a role. TL1A has been linked to inflammatory bowel disease. The 5G4.2 antibody has been shown to block TL1A binding to DR3 and reduce disease severity in mouse models of colitis.
