Description
CD40 is an immune costimulatory receptor central to antigen-presenting cell–T cell/B cell interactions; CD40–CD40L signaling is a canonical axis for adaptive immune activation and downstream inflammatory transcriptional programs (clinical context: immune activation and autoimmunity research, putative). Assay context: validated for WB in mouse; frequently interpreted together with CD40L (CD40LG) and B-cell survival ligands/receptors such as BAFF and BCMA.
Storage & Handling
Store at -20˚C for one year from date of receipt. After reconstitution, at 4˚C for one month. It can also be aliquotted and stored frozen at -20˚C for six months. Avoid repeated freeze-thaw cycles.

Background of Cd40
CD40 is a cell surface receptor that is expressed on the surface of all mature B cells and also expressed on monocytes, dendritic cells, and thymic epithelium. CD40 is a member of the tumor necrosis factor (TNF) receptor superfamily and is the receptor for CD40 ligand. CD40 ligand (CD40L, CD154, gp39, and TRAM) belongs to the TNF gene family and is expressed more widely than CD40 predominantly on activated CD4+ T cells. Activation of CD40 has also been shown to inhibit the growth of certain B cell lymphomas and to induce the death of transformed cells of mesenchymal or epithelial origin.
Antibody Validation

4 Customer Q&As for Anti-CD40 Antibody Picoband®
Question
We are currently using anti-CD40 antibody PA1019 for mouse tissue, and we are well pleased with the WB results. The species of reactivity given in the datasheet says mouse. Is it true that the antibody can work on bovine tissues as well?

Answer
The anti-CD40 antibody (PA1019) has not been tested for cross reactivity specifically with bovine tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in bovine you can get your next antibody for free. Please contact me if I can help you with anything.

Question
We have observed staining in mouse ovary. Do you have any suggestions? Is anti-CD40 antibody supposed to stain ovary positively?
G. Johnson
Verified customer
Asked: 2013-08-02
Answer
According to literature ovary does express CD40. According to Uniprot.org, CD40 is expressed in left coronary artery, kidney, ovary, leukocyte, lymphoma urinary bladder carcinoma, among other tissues. Regarding which tissues have CD40 expression, here are a few articles citing expression in various tissues:

Question
My team were well pleased with the WB result of your anti-CD40 antibody. However we have observed positive staining in left coronary artery isoform i: cell membrane using this antibody. Is that expected? Could you tell me where is CD40 supposed to be expressed?
K. Bhatt
Verified customer
Asked: 2013-04-30
Answer
From literature, left coronary artery does express CD40. Generally CD40 expresses in isoform i: cell membrane. Regarding which tissues have CD40 expression, here are a few articles citing expression in various tissues:
