Used in immunological research to quantify membrane-bound immunoglobulin M (mIgM) on human B cells. Enables detection and measurement of B cell activation and differentiation in clinical studies and immunology labs. Supports investigation of autoimmune diseases, immunodeficiency disorders, and B cell malignancies. Commonly applied in vaccine development and therapeutic antibody research to assess humoral immune responses. Provides a reliable, high-throughput method for monitoring mIgM expression in cell cultures and patient samples.
