Background information
Using this kit FoxP3 expression by Treg cells is sustained after isolation with the CD4+ CD25+ Regulatory T cell Isolation Kit, CD4+ CD25+ CD127dim/– or CD4+ CD25+ CD45RA+ Regulatory T Cell Isolation Kits from human blood or PBMCs. The kit is also suitable for usage with rapamycin.
The Treg Expansion Kit is based on MACSiBead™ Particles pre‑loaded with CD3 and CD28 antibodies. Optimal expansion of Treg cells is accomplished by using pre-loaded MACSiBead Particles and Treg cells at a bead-to-cell ratio of 4:1 and recombinant interleukin 2 (rIL-2) with a concentration of 500 U/mL.
Downstream applications
Expansion of human Treg cells after isolation with the CD4+ CD25+ CD127dim/– or CD4+ CD25+ CD45RA+ Regulatory T Cell Isolation Kits from human blood or PBMCs. Expanded Treg cells can be used for any downstream application such as cytokine analysis, gene expression, and suppression assays.
