{"product_id":"biolegend-422604","title":"Biolegend, 422604, Human CD3\/CD28 T Cell Activation Beads, VO22","description":"\u003cp\u003eThe Human CD3\/CD28 T Cell Activation Beads allow for convenient in vitro activation of human T cells without the need for antigen-presenting cells. Human T cells are stimulated with anti-CD3 and anti-CD28 antibodies coated on superparamagnetic microbeads. Simply add the beads directly to isolated T cells or to PBMCs at a 1:1 particle-to-cell ratio for robust T cell activation. The antibody-coated beads can be removed from the cells by the use of a magnetic separator. Some of the downstream applications include functional assays, gene expression analysis, and phenotypic characterization.\u003cbr\u003e\nVO22\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nFormulation: Cocktail: N\/AParticle: Phosphate buffer solution containing 0.1% HSA (azide-free).
