Human CD19 B Cells for Immunology and Antibody Research
Human CD19+ B cells are purified from peripheral blood of healthy and clinically confirmed disease-state donors and are designed to support a wide range of immunology and translational research applications. These cryopreserved cells enable studies of B cell biology, antibody production, B cell receptor signaling, immune regulation, and disease-associated immune dysfunction.
Whether your team needs healthy donor controls, disease-state CD19+ B cells, or custom donor-defined programs, Sanguine helps researchers source human CD19 B cells aligned to protocol requirements and downstream assay needs.
