High-Quality Healthy CD19 B Cells for Immunology and Antibody Research

Healthy CD19 B Cells are purified from peripheral blood of healthy, IRB-consented adult donors. These B lymphocytes are essential for humoral immunity and serve as a critical model for studying antibody production, B cell receptor (BCR) signaling, and immune regulation in health and disease. Offered fresh or cryopreserved, these cells support diverse applications in immunology, oncology, and therapeutic development.
