I found you also have anti-human CD38 mAb that can be used for neutralization. If I understood correctly, it means that these antibodies can block the surface expression of CD38 in human cells such as CD4+T cells? Because now I am searching for anti-human CD38 antibody to be used in the cell culture to block the surface expression of CD38. Is it possible?
Sorry, but we don't carry these ourselves, I was just suggesting possible blocking CD38 clones. You will need to check with the actual suppliers for details about the suitability for your application.
