Human T Cell Activation and Expansion
| Ready-to-use Dynabeads® allows for simultaneous signalling to TCR/CD3 and CD28 for physiological activation and expansion of human T cells. See our new product for expansion of human antigen specific T cell lines or clones Dynabeads® Human T-Activator CD3/CD28/CD137 This technology out-performs traditional home-brew activation methods (mitogens, ConA, soluble antibodies etc.), and is well documented in the published literature. |
Dynabeads® allow you to move from mouse studies to clinical research using the same technology platform for activation/expansion .
Here's a short overview of the available products. For a more complete overview, check out this Product Selection Guide (pdf).
