Anti-hCD40L-lgG

Neutralizing monoclonal antibody against human CD40L

Neutralizing monoclonal antibody against human CD40L

Anti-hCD40L-IgG is a monoclonal mouse IgG2b antibody specific for human CD40 ligand (hCD40L). This antibody was generated by InvivoGen using DNA immunization. It has been produced in hybridomas and purified by affinity chromatography.

This antibody has been selected for its ability to efficiently neutralize the biological activity of hCD40L. CD40 Ligand (CD40L) is a protein that is primarily expressed on activated T cells and is a member of the tumor necrosis factor superfamily. Of note, CD40L, together with its receptor CD40, plays a pivotal role in cellular and humoral immunity [1-3].

Details

CD40 Ligand (CD40L), also known as CD154, TRAP, or gp39, is a type II transmembrane glycoprotein belonging to the tumor necrosis factor (TNF) family. It is mainly expressed in CD4+-T cells and interacts with CD40 on antigen-presenting cells to regulate both humoral and cellular immune responses [1-3].

The CD40 cytoplasmic domain binds directly to several TNF receptor-associated factors (TRAFs), and this interaction is thought to initiate CD40 signaling. CD40-mediated signaling results in NF-κB, c-Jun N-terminal kinase (JNK), and p38 mitogen-activated protein kinase (MAPK) activation. CD40L-CD40 interactions are thought to play an important role in the pathogenesis of many diseases [4, 5].
