TargetMols Human CD3/CD28 T Cell Activation Magnetic Beads are a convenient and efficient tool for activating and expanding T cells without the need to rely on feeder cells (e.g., antigen-presenting cells) or antigens. The beads are 5 µm in diameter, made of an inert superparamagnetic material, comparable in size to antigen-presenting cells, and covalently coupled with anti-CD3 and anti-CD28 antibodies. Expansion of the T cell population can be promoted in cell culture by the addition of recombinant human IL-2. After activation and expansion, the magnetic beads can be easily removed using a magnetic rack.
