The Quantikine Human CD40 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human CD40 in cell culture supernates, serum, plasma, saliva, urine, and human milk. It contains NS0-expressed recombinant human CD40 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human CD40 showed linear curves that were parallel to the standard curv...es obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human CD40.

Background
CD40, also known as TNFRSF5, is a transmembrane TNF superfamily receptor that is expressed on the surface of B cells, dendritic cells, macrophages, monocytes and platelets, as well as endothelial and epithelial cells. Interaction of CD40 with CD40 Ligand leads to the aggregation of CD40 molecules resulting in the initiation of bidirectional intracellular signaling in both CD40 and CD40 Ligand expressing cells. This interaction promotes B cell activation and T cell-dependent humoral responses. CD40 serves multiple functions in both hematopoietic and epithelial cancers and is a target for tumor immunotherapy. Dysregulation of CD40/CD40 Ligand expression and interactions contributes to disease severity in AIDS, atherosclerosis, atherothrombosis, and restenosis.

FAQs for CD40/TNFRSF5 (DCCD40). (Showing 1 - 2 of 2 FAQs).
I wanna know does CD40 antibody for IHC-P comes with positive control slide?
Our CD40 antibodies do not come with positive control slides however you can use any type of primary carcinoma cell as a positive control. I recommend breast carcinoma as this is what we have tested our CD40 antibodies on.
We are studying CD40L in our system. It has been known that both CD40 and CD11b are receptors for CD40L. We need CD40 antibody to neutralize CD40 binding to CD40L, then we may prove what is function for CD11b binding to CD40L. Do you have any CD40 Ab which has block function only between CD40 and CD40L, but not between CD11b and CD40L?
Unfortunately, none of our CD40 antibodies have been specifically tested for this application.
