human CD3/CD28 activates magnetic beads

Human CD3/CD28 Activation Magnetic Beads are superparamagnetic beads covalently bound with anti-human CD3 and CD28 monoclonal antibodies, designed to mimic the natural activation of T cells through antigen-presenting cell (APC) signaling. These beads enable robust and reproducible ex vivo activation and expansion of human T lymphocytes, making them essential in immunology, CAR-T, and adoptive cell research.
