Reactivity Notes



CD40 ligand (CD40L) is a 33 kDa type II membrane glycoprotein expressed mainly on the cell surface of activated T lymphocytes, but also exists as a soluble form extracellularly. CD40L is the ligand for CD40, a member of the TNF superfamily, which is expressed on the cell surface of B cells, macrophages/monocytes, dendritic cells, vascular endothelial cells, and epithelial cells. CD40L plays an important role in B cell proliferation, antibody class switching, modulation of apoptosis in the germinal center through interaction with B cells expressing CD40, and activation of CD4+ T cells. Mutation within the CD40L gene is linked to hyper IgM syndrome, an X linked immunodeficiency disease that is characterized by elevated level of serum IgM and decreased level of other isotypes.

FAQs for CD40 Ligand/TNFSF5 Antibody (NB100-73094). (Showing 1 - 1 of 1 FAQ).

  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 with any questions regarding this program.
