Ontology

Protein Function Receptor for TNFSF5/CD40LG. Transduces TRAF6- and MAP3K8-mediated signals that activate ERK in macrophages and B cells, leading to induction of immunoglobulin secretion.
Research Areas Human

Background 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.

Customer Q&As

  • Q: Do you offer BSA-free antibodies? Keyword: Bovine serum albumin, carrier protein, conjugation
    A: Yes, please contact us at [email protected] for more information about BSA-free antibodies and availability. The new BSA-free formula uses trehalose as a replacement to BSA. We have tested many alternative chemicals and found that trehalose protects the antibodies the best.
  • Q: Is your western blot protocol provided from the website applicable for all your antibodies? Keyword: applications, WB
    A: The protocol is applicable for all our antibodies in WB, the NC Membrane(0.45μm or 0.22μm) and transfer time(70 mins or 50 mins) depends on the protein molecular weight, details can be found in included protocol.
  • Q: Can I conjugate markers to this antibody? Can I link custom conjugates to this antibody? Keyword: conjugation
    A: The antibody is stored with BSA and cannot be conjugated with markers. Carrier free antibodies are available upon request. Please contact [email protected]
  • Q: How come some of your antibodies have more than one catalog numbers for the same target? One example is anti-CD40 antibody which has two catalog numbers: PA1019, PA1019-1.
    A: It is because for some targets we have at least two antibodies with different immunogen sequences to target different epitopes and/or species. For the case of anti-CD40 antibody, PA1019 has an immunogen N-terminus of mouse CD40 (22-36 aa, QCVTCSDKQYLHDGQ), while the immunogen for PA1019-1 is N-terminus of human CD40 (20-37 aa, PEPPTACREKQYLINSQC).
  • Q: What should I use for negative control?
    A: Please contact us for negative control suggestions. You can also check expression databases such as genecards, uniprot etc. Due to logistic reasons, we do not sell serum or lysates that we use internally for positive or negative control.
  • Q: Where can I find troubleshooting information? What should I do if I have unexpected bands, high background, no signal, weak signal
    A: You can find Boster's troubleshoot guides under tech support tab. Please contact us for further assistance on troubleshooting your experiment.
  • Q: What is the immunogen sequence of this antibody? Is this antibody polyclonal or monoclonal?
    A: You can find the immunogen sequence under "
  • Q: What is the expected band size? Why is it different than the observed band size?
    A: The expected band size is predicted on the size of the protein. The actual band size may be affected by a few other factors including but not limited to:<br>1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected<br>2. Post-translational cleavage: this can cause smaller bands and or multiple bands <br><br>3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody. <br><br>4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.<br>5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher., <br>
  • Q: What is the suggested dilution ratio for Western Blot (WB), Immunohistochemistry (IHC) and or ELISA standards? What is the optimal pH for the sample?
    A: Check the datasheet for the product for details on dilution ratios for different experiments. You can find the datasheet button on the right side of the product page.
  • Q: What is the protocol you used for your Western blotting (WB) and Immunohistochemistry (IHC)?
    A: Check our protocols under the tech support tab.
