FOXP3 Mouse anti-Human, Mouse, Clone: eBio7979, eBioscience
Mouse Monoclonal Antibody
Manufacturer: Invitrogen 14797982
Description: eBioscience offers a panel of monoclonal antibodies to different epitopes of human and mouse Foxp3, providing useful tools for investigating the complete expression pattern of Foxp3 at the protein level, and discerning the precise subsets of Foxp3+ cells. Other antibodies to human Foxp3 include PCH101 (cat. 72-5776) and 236A/E7 (cat. 12-4777). Additional antibodies to mouse Foxp3 include FJK-16s (cat. 72-5775) and NRRF-30 (cat. 12-4771). The eBio7979 antibody reacts with human and mouse foxp3 protein also known as FORKHEAD BOX P3, SCURFIN, and JM2; cross reactivity of this antibody to other proteins has not been determined. Foxp3, a 49-55 kDa protein, is a member of the forkhead/winged-helix family of transcriptional regulators, and was identified as the gene defective in ft.scurfy ft. (sf) mice. Constitutive high expression of Foxp3 mRNA has been shown in CD4+CD25+ regulatory T cells (Treg cells), and ectopic expression of foxp3 in CD4+CD25- cells imparts a Treg phenotype in these cells. Please see our FAQ regarding the usage of eBioscience Foxp3 reagents. Applications Reported: This eBio7979 antibody has been reported for use in immunoblotting (WB). Applications Tested: This eBio7979 antibody has been tested by immunoblotting of normal human peripheral blood mononuclear cell lysates at 1-2 µg/mL. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 µm post- manufacturing filtered. FOXP3 (Forkhead box protein 3) is a member of the forkhead/winged-helix family of transcriptional regulators, highly conserved across mammals, and essential for normal immune homeostasis. FOXP3 is 381 amino acids long, stably and constitutively expressed at a high level in CD25 + CD4 positive regulatory T cells, a low level in CD4-positive/CD25-negative cells, and is absent in CD4-negative/CD8-positive T cells. FOXP3 may be a master regulatory gene, and a more specific marker of regulatory T cells. Defects in the gene encoding FOXP3 protein cause the scurfy phenotype in mice. In humans FOXP3 defects play a role in IPEX syndrome (immune dysfunction, polyendocrinopathy, enteropathy, X-linked syndrome), also known as X-linked autoimmunity-allergic dysregulation (XLAAD) syndrome. Transcript variants of FOXP3 encoding different isoforms have been identified. In human breast and colon cancer cells, expression of FOXP3 is regulated by p53 in response to the DNA damage.
