Product DescriptionImmunoCult™ Human CD3/CD28 T Cell Activator is designed to activate and expand human T cells in the absence of magnetic beads,feeder cells, or antigen. ImmunoCult™ Human CD3/CD28 T Cell Activator consists of soluble antibody complexes that bind CD3 and CD28cell surface ligands. Binding of the antibody complexes results in the cross-linking of CD3 and CD28 cell surface ligands, thereby providingthe required primary and co-stimulatory signals for T cell activation. Activated T cells can be expanded in ImmunoCult™-XF T CellExpansion Medium (Catalog #10981) or other media for culturing human T cells supplemented with cytokines.• Robust activation and expansion of human T cells without the use of magnetic beads, feeder cells, or antigen• Provides a gentle activation stimulus that maintains high viability of activated and expanded T cells• Highly stable, filter-sterilized soluble reagentPropertiesStorage: Store at 2 - 8°C.Shelf Life: Stable until expiry date (EXP) on label.Contains: • Anti-human CD3 monospecific antibody complex• Anti-human CD28 monospecific antibody complex
