The CD4
+
CD25
+
Regulatory T Cell Isolation Kit was developed for the isolation of CD4
+
CD25
+
cells from human PBMCs. The isolation is performed in a two-step procedure.

Background information

Regulatory CD4
+
CD25
+
T cells are suppressor cells that neutralize other immune cells by various mechanisms. Their characteristic marker is the transcription factor FoxP3. Regulatory CD4
+
CD25
+
T cells seem to suppress harmful immunological reactions to self or foreign antigens.

Detailed separation procedure

The isolation is performed in a two-step procedure. First, non-CD4
+
T cells are indirectly magnetically labeled with a cocktail of biotin-conjugated antibodies against CD8, CD14, CD15, CD16, CD19, CD36, CD56, CD123, TCRγ/δ and CD235a (glycophorin A) 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
+
T cells is labeled with CD25 MicroBeads for subsequent positive selection of CD4
+
CD25
+
regulatory T cells.

Downstream applications

The CD4
+
CD25
+
Regulatory T Cell Isolation Kit has been used to investigate the role of CD4
+
CD25

regulatory T cells in autoimmune diseases

, allergy

, and in infectious diseases

. For further characterization, CD4

CD25
+
regulatory T cells were isolated from patients suffering from rheumatoid arthritis

or multiple sclerosis
2
, from acute T cell lymphoma patients
