QA18A03_PURE_FOXP3_RECOM_Anitbody_051721.png
Human peripheral blood lymphocytes were surface stained with CD4 APC and then treated with True-Nuclear™ Transcription Factor Buffer Set. Cells were then intracellularly stained with purified anti-human FOXP3 recombinant (clone QA18A03) (left) or purified mouse IgG1, κ isotype control (right), followed by anti-mouse IgG PE secondary antibody.

Description

FOXP3 is a 50-55 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. In human, unlike in mouse, two isoforms of FOXP3 have been reported: one (FOXP3) corresponding to the canonical full-length sequence; the other (FOXP3 δ2) lacking exon 2.

Related FAQs

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.
