Total cell lysates (15 µg protein) from 293E untransfected (lane 1), 293E transfected with human FOXP3 (lane 2), and 293E transfected with human FOXP3 Delta2 (lane 3) were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to nitrocellulose, and probed with 0.1 µg/mL purified anti-FOXP3 Delta 2 (exon 2 deleted) antibody (clone A15080A). Proteins were visualized using an HRP goat anti-mouse-IgG secondary antibody (clone Poly4053) and chemiluminescence detection. Direct-Blot™ HRP anti-β-actin antibody (clone 2F1-1) was used as a loading control.

Description

FOXP3 is a transcription factor which 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 delta 2) lacking exon 2. This antibody reacts to human FOXP3 delta 2 (exon 2 deleted) form and weakly reacted to the full-length FOXP3.

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.
