Human CD40L Antibody

Mouse IgG2a (clone 13H5) - Recombinant

ABOUT

Recombinant anti-human CD40L neutralizing antibody

Anti-hCD40L-mIgG2a is a monoclonal antibody (mAb) targeting the human CD40 ligand (CD40L). This mAb specifically blocks the binding between CD40L to its receptor CD40, validated using proprietary CD40L reporter cells.

Anti-hCD40L-mIgG2a is a monoclonal antibody (mAb) targeting the human CD40 ligand (CD40L). This mAb specifically blocks the binding between CD40L to its receptor CD40, validated using proprietary CD40L reporter cells. Anti-hCD40L-mIgG2a was previously extracted from hybridoma cells (clone 13H5). It is now expressed and produced in Chinese hamster ovary (CHO) cells, ensuring reliability and lot-to-lot reproducibility. This antibody can be used together with HEK-Blue™ CD40L cells for screening and neutralization assays to block CD40L signaling induced by recombinant human CD40L (see figure).

 

Key features

  • Each lot is functionally tested and validated.
  • The complete sequence of the antibody construct has been verified.
  • The absence of endotoxins is determined by the EndotoxDetect™ assay.

 

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.

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].
