FOXP3 is a 47 kD transcription factor, also known as Forkhead box protein P3, Scurfin, JM2, or IPEX. It is proposed to be a master regulatory gene and more specific marker of T regulatory cells than most cell surface markers (such as CD4 and CD25). Transduced expression of FOXP3 in CD4+/CD25- cells has been shown to induce GITR, CD103, and CTLA4 and impart a T regulatory cell phenotype. FOXP3 is mutated in X-linked autoimmunity-allergic dysregulation syndrome (XLAAD or IPEX) in humans and in "scurfy" mice. Overexpression of FOXP3 has been shown to lead to a hypoactive immune state suggesting that this transcriptional factor is a central regulator of T cell activity.Product Details

- Can I stain whole blood with anti-FOXP3 using your Foxp3 staining kit?
It is not recommended. It is best to use PBMCs for this testing.
- Can FOXP3 be costained with cytokines?
The larger holes created by the nuclear permeabilization required for FOXP3 may allow cytokines to leak out of the cell, making it harder to detect lowly-expressed cytokines. You may have to use a control where the cells are only permeabilized through the cell membrane.
