The CD4
+
CD25
+
CD45RA
+
Regulatory T Cell Isolation Kit was developed for the isolation of CD45RA
+
regulatory T cells (Treg) from human PBMCs in a two-step procedure.

Background information

Regulatory CD4
+
CD25
+
T cells isolated from the CD45RA
+
naive T cell compartment were shown to be optimal for
in vitro
expansion. These expanded Treg cells maintained the FoxP3
+
phenotype and their suppressive activity, whereas CD45RA
regulatory T cells from the memory T cell compartment lost FoxP3 expression and showed only modest suppressive activity.

Detailed separation procedure

The isolation is performed in a two-step procedure. First, non-CD4
+
and memory T cells are indirectly magnetically labeled with a cocktail of biotin-conjugated antibodies and Anti-Biotin MicroBeads. The labeled cells are subsequently depleted over a MACS
®
Column. In the second step, the flow-through fraction of pre-enriched CD4
+
CD45RA
+
T cells is labeled with CD25 MicroBeads for subsequent positive selection of CD4
+
CD25
+
CD45RA
+
T cells.

Downstream applications

CD4
+
CD25
+
CD45RA
+
regulatory T cells can be isolated from human PBMCs with this kit, for example, for further phenotypical or functional characterization and expansion.
