Used in the development and validation of biotherapeutic drugs targeting CD38, this reference antibody serves as a critical tool in immunological research and drug discovery. It enables accurate measurement of binding affinity, specificity, and functional activity in assays such as flow cytometry, ELISA, and surface plasmon resonance. Due to its well-characterized properties, it is employed as a benchmark in comparative studies for evaluating therapeutic monoclonal antibodies in diseases like multiple myeloma and other CD38-expressing hematologic malignancies. It also supports quality control during manufacturing and helps ensure consistency and reliability in clinical testing.
