{"product_id":"biolegend-320002","title":"Biolegend, 320002, Purified anti-mouse\/rat\/human FOXP3 Antibody, 100μg","description":"\u003cp\u003eFOXP3 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. The 150D monoclonal antibody reacts with human, mouse and rat FOXP3. The 150D antibody recognizes FOXP3 epitope encoded by exon 2.\u003cbr\u003e\n100μg\u003cbr\u003e\nVerified Reactivity: Human, Mouse, Rat\u003cbr\u003e\nReported Reactivity: Cynomolgus, Rhesus, Baboon\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: Full-length FOXP3 protein\u003cbr\u003e\nFormulation: This antibody is provided in phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography.\u003cbr\u003e\nConcentration: 0.5 mg\/ml\u003cbr\u003e\nStorage \u0026amp; Handling: Upon receipt, store undiluted between 2°C and 8°C.\u003cbr\u003e\nApplication: WB - Quality tested ICFC - Reported in the literature, not verified in house\u003cbr\u003e\nRecommended Usage: Each lot of this antibody is quality control tested by immunofluorescent intracellular staining with flow cytometric analysis.
