Dynabeads for human T Cell expansion

Ready-to-use Dynabeads will allow you to optimize ex vivo T cell activation and proliferation in translational research, while preserving T cell viability and optimal immune function. Simultaneous signaling to TCR/CD3 and CD28 triggers a physiological activation and expansion of human T cells. You can also stimulate and expand human antigen-specific T cell lines or clones using Dynabeads Human T-Activator CD3/CD28/CD137.

This simple, efficient and consistent technology out-performs and replaces traditional home-brew methods for generic activation based on antigen-presenting cells (APCs), mitogens (e.g. ConA, PHA), soluble/plate-bound antibodies, or chemical activators, and is well documented in published literature. Expansion and re-infusion of genetically engineered T cells has the potential to revolutionize the treatment of leukemia and related blood cancers. A clinical research grade version is also available, allowing you to move from mouse studies to clinical research using the same technology platform.
