CD38 (cyclic ADP-ribose hydrolase 1, ADPRC1) is a glycoprotein and ectoenzyme which plays an important role in regulating intracellular calcium. CD38 is a highly attractive target antigen for immunotherapy because it is highly expressed on multiple myeloma cells, and at relatively low levels on normal lymphoid and myeloid cells. Expression of CD38 has also been associated with HIV infection, leukemia, and type II diabetes mellitus. CD38 CAR-T is a T cell product engineered by retroviral transduction to express a fully human CD38-specific CAR (chimeric antigen receptor). In 2015, the FDA approved daratumumab (Darzalex), a breakthrough therapy drug targeting CD38, for the treatment of multiple myeloma.
Recombinant clonal stable CHO cell line constitutively expressing full length human CD38 protein, also known as ADPRC1 (Genbank #NM_001775). Surface expression of CD38 was confirmed by flow cytometry. Each stable clonal cell line was selected for different levels of CD38 expression (High, Medium, Low) to mimic different stages of cancer target cells with various CD38 expression levels.
