Anti-CD38 monoclonal antibodies continue to demonstrate promising results as new treatments for patients with multiple myeloma. Therapeutic anti-CD38 targets this molecule, highly expressed on the surface of multiple myeloma cells, hampering its detection by flow cytometry.

Cytognos has developed an anti-human CD38 multi-epitope reagent containing a mixture of antibodies that allows the identification by flow cytometry of CD38 molecule on plasma cells, even in patients under anti-CD38 therapy.
