Ready-to-use Dynabeads™ allows for simultaneous signalling to TCR/CD3 and CD28 for physiological activation and expansion of mouse T cells. 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.

Product Starting sample Main benefits
Dynabeads Mouse T-Activator CD3/CD28 (0.4 ml)

Dynabeads Mouse T-Activator CD3/CD28 (2 ml)

Dynabeads Mouse T-Activator CD3/CD28 (10 ml)
Mouse spleen or lymph node cells, mouse T cell clones, mouse CD4+ and CD8+ T cell subsets. Artificial antigen-presenting cells, optimized for mouse T cell activation and expansion.

Also includes a new protocol for mouse Treg expansion.

For isolation of T cells prior to T cell activation, we offer a range of Dynabeads for both positive and negative isolation. See the selection guide
