A complete workflow for activation and expansion of your T cells

Optimize ex vivo T cell activation and expansion in translational research, while preserving functionality and viability. After gentle T cell isolation with our MACS® Technology solutions, activation can be either performed polyclonally or antigen-specific. Efficient and reliable proliferation ensures viable and functional T cells for any downstream application. 

Our flow cytometry solutions enable highly accurate multiparameter T cell analysis.

 

Application data by workflow step

T cell isolation

Streamlined magnetic T cell isolation with MACS® Technology

Reliability now comes with better performance and faster protocols. Our improved MicroBeads and T Cell Isolation Kits allow for high-quality separation of  human and mouse T cells within a few minutes.

MACS MicroBeads

  • Updated CD4, CD8a, CD90.1 and CD90.2 MicroBeads, mouse allow for positive selection of T cells in only 13.5 minutes

  • MicroBeads are available with many human, mouse, rat and non-human primate specificities


T cell isolation kits

  • Untouched isolation of human and mouse T cells and T cell subsets in as little as 18 minutes

T cell isolation directly from blood products

StraightFrom® MicroBeads allow magnetic cell separation directly from human blood products, such as whole blood, buffy coat, leukoreduction system chambers (LRSCs) and leukopaks. CD4+ and CD8+ T cell subsets can be purified using the autoMACS® Pro Separator, the MultiMACS™ Cell24 Separator Plus, or manual separators.

  • Easy and fast protocols with only a few handling steps
  • No cell activation and no effects on cell biology

 

Label-free T cell isolation

REAlease® Technology allows for magnetic cell isolation with subsequent removal of any beads and labels from your cells of interest. Clever utilization of recombinant antibody fragments allows for cell surface labeling in just a few steps. 

The technology relies on recombinantly engineered antibody fragments for cell surface labeling for highly reproducible results. The REAlease Biotin Complex binds to the target cells. Labeling of the REAlease Biotin Complex with Anti-Biotin MicroBeads allows for magnetic isolation of these cells. Following cell separation, both MicroBeads and REAlease Biotin Complex are gently removed, leaving the cells bead-and label-free. Enriched cells are then suitable for magnetic re-labeling and any application where label-free cells are essential.
