Polyclonal stimulation reagents for cell expansion and activation
Polyclonal stimulation, the activation of cells regardless of their specificity, can be achieved in different ways with our products.
Our MACSiBead™ Particles, as used in our Activation/Expansion Kits, are antibody-loaded particles that mimic antigen-presenting cells. This technology is suited for cell stimulation and expansion of various cell types, including T cells, Treg cells, or NK cells and can also be used in suppression assays. Specially developed for T cell stimulation, we offer T Cell TransAct™ Reagent and CytoStim™ Reagent: T Cell TransAct Reagent is a polymeric nanomatrix pre-loaded with CD3 and CD28 agonists, and CytoStim Reagent is an antibody-based reagent that acts similarly to a superantigen.
