W17212H_ULEAF_CD40_Antibody_1_083019_updated
Recombinant biotinylated hCD40L (Black circles) binds to immobilized recombinant hCD40 (Cat. No. 777206). Anti-hCD40 antibody (clone W17212H, Purple squares) inhibits the binding in a dose-dependent manner whereas the Isotype control (Cat. No. 400666, Green triangles) doesn’t have the effect. This antibody blocks the binding of 80 ng/mL hCD40L biotinylated protein to 1 µg/mL immobilized recombinant hCD40 with an ND50 = 0.2 - 1 µg/mL.

Description

CD40, also known as TNFRSF5, is a type I transmembrane protein that belongs to the TNF receptor family (TNFR). CD40 is expressed on B cells, dendritic cells, monocytes, macrophages, platelets, basal epithelial cells, endothelial cells and a subset of CD34+ hematopoietic progenitors. The interaction between CD40 and its ligand TNFSF5/CD40L leads to the clustering of CD40 and the recruitment of TNFR associated factors (TRAFs), including TRAF1, 2, 3, 5 and 6. TRAF1, 2, 5 and 6 serve as positive regulators while TRAF3 is a negative regulator. CD40/CD40L interaction triggers downstream signaling on both cells, including upregulation of CD40 and cell survival on dendritic cells, upregulation of co-stimulatory molecules, CD80 and CD86 on T cells, and production of inflammatory cytokines. In addition, CD40 regulates B cell development/maturation, Ig isotype switching and in combination with other signals such as IL-4, promotes proliferation. It has been reported that a transcriptional factor, AKNA, can coordinately regulate the expression of CD40 and CD40L. Dysregulation of CD40 is associated with several diseases, such as hyper-IgM immunodeficiency type 3 (HIGM3) and Hodgkin's disease. Targeting of CD40/CD40L for cancer therapy is being evaluated in clinical trials, including anti-CD40 agonist antibodies and soluble recombinant CD40L. Several isoforms have been identified in humans and mice.

Related FAQs

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each Ultra-LEAF™ antibody by functional assay?

No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
