Description
ActSep® CD3/CD28 Separation & Activation Magnetic Beads are suitable for separation of human CD3+ T cells, providing a simple method for activating and expanding human T cells without the need for antigen presenting cells and antigens.
By coupling anti-human CD3 and anti-human CD28 antibodies on magnetic beads, the primary and co-stimulatory signals needed to regulate T cell activation and expansion are provided.
The beads are suitable for human T cell separation, activation and expansion, CAR-T, and other T cell culture applications.
