Hopefully someone else will provide you with a specific recommendation based on personal use, but if not, we can certainly suggest many possible sources for anti-CD38 for WB: https://www.linscottsdirectory.com/antibodies?q=cd38
just select "human" and "WB" from Reactivity and Applications filters. Follow "more info" to suppliers' data pages.
I have never done Western anaylsis on CD38, but I have had excellent results with HIT-2 for flow cytometry, I suspect it would be usable in blots as well.
You may check an antibody database at Labome.com. Here is the link to the database page for anti-CD38 antibodies: https://www.labome.com/review/gene/human/CD38-antibody.html. Santa Cruz Biotechnology has several antibodies to human CD38 suitable for Western blot: C-19 (sc-7047) and H-11 (sc-374650) (ref.: Escande et al., J Clin Invest 2010). Also, BD Biosciences provides mouse monoclonal 22/CD38 antibody for Western blot (ref.: Bunaciu et al., PLos One 2015).
Targeting CD38 by isatuximab can preferentially block immunosuppressive Tregs and thereby restore immune effector function against multiple myeloma.
Daratumumab targets CD38-expressing myeloma cells through a variety of immune-mediated mechanisms (complement-dependent cytotoxicity, antibody-dependent cell-mediated cytotoxicity, and antibody-dependent cellular phagocytosis) and direct apoptosis with crosslinking. These mechanisms may also target nonplasma cells that express CD38, which prompted evaluation of daratumumab's effects on CD38-positive immune subpopulations.
Another work assessed the antitumor activity of the anti-CD38 antibody SAR650984 and the results validate CD38 as a therapeutic target and support the current evaluation of this unique CD38-targeting functional antibody in phase I clinical trials in patients with CD38+ B-cell malignancies.
Thank you for your responses. But daratumumal is too expensive, as my experiment is at the initial stage. I would like to use less expensive antibody, that can not be therapeutic. Do you have any other recommendations?
