TargetMols Mouse CD3/CD28 T Cell Activation Beads are a convenient and efficient tool for activating and expanding T cells without the need for feeder cells (such as antigen-presenting cells) or antigens. The beads are 5 µm in diameter, made of inert superparamagnetic material, and are comparable in size to antigen-presenting cells. They are covalently conjugated with anti-CD3 and anti-CD28 antibodies. In cell culture, the addition of recombinant mouse IL-2 can further promote the expansion of the T cell population. After activation and expansion, the beads can be easily removed using a magnetic separator.
