{"product_id":"biolegend-694802","title":"Biolegend, 694802, Purified anti-human FOXP3 Delta 2 (exon 2 deleted) Antibody, 100μg","description":"\u003cp\u003eFOXP3 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.\u003cbr\u003e\n100μg\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: Human FOXP3 delta2 (exon 2 deleted) peptide conjugated to KLH.\u003cbr\u003e\nFormulation: 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: The antibody solution should be stored undiluted between 2°C and 8°C.\u003cbr\u003e\nApplication: WB - Quality tested\u003cbr\u003e\nRecommended Usage: Each lot of this antibody is quality control tested by Western blotting.

You may have to use a control where the cells are only permeabilized through the cell membrane.\u003c\/p\u003e","brand":"Biolegend","offers":[{"title":"Default Title","offer_id":46864385081513,"sku":"694802","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/biolegend-694802","provider":"Iright","version":"1.0","type":"link"}
