CD40 Ligand/TNFSF5 Antibody [Unconjugated]

Western blot shows conditioned media (CM) from Th17 cells. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human CD40 Ligand/TNFSF5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF617) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for CD40 Ligand/TNFSF5 at approximately 17 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background

CD40 ligand, CD40L (also known as CD154, TRAP or gp39), is a 261 amino acid type II transmembrane glycoprotein belonging to the TNF family, CD40L is expressed predominantly on activated CD4⁺ T lymphocytes, and also found in other types of cells, like NK cells, mast cells, basophils and eosinophils. Human CD40L shares 78% amino acid identity with its murine counterpart. The receptor of CD40L is CD40, a type I transmembrane glycoprotein belonging to the TNF receptor family. CD40 is expressed on B lymphocytes, monocytes, dendritic cells and thymic epithelium. Although all monomeric, dimeric and trimeric forms of soluble CD40L can bind to CD40, the trimeric form of soluble CD40L has the most potent biological activity through oligomerization of cell surface CD40, a common feature of TNF receptor family members. CD40L mediates a range of activities on B cells including induction of activation-associated surface antigen, entry into cell cycle, isotype switching and Ig secretion and memory generation. CD40-CD40L interaction also plays important roles in monocyte activation and dendritic cell maturation.

FAQs for CD40 Ligand/TNFSF5 Antibody (AF617). (Showing 1 - 1 of 1 FAQs).

1. I am looking for paired ABs for use in detecting CD40L (rat) by ELISA. Do you have such a reagent(s) available?
   • Unfortunately we currently do not have any CD40 Ligand antibody pairs that have been validated in Rat. The only antibody pairs we offer for CD40L are validated in Human. I apologize for this inconvenience. If you would be interested in testing one of our products in Rat I'd like to invite you to participate in our Innovators Reward Program. Please contact us at innovators@novusbio.com with any questions regarding this program.
