{"product_id":"biolegend-125005","title":"Biolegend, 125005, FITC anti-mouse FR4 (Folate Receptor 4) Antibody, 50μg","description":"\u003cp\u003eFolate receptor 4 (FR4) is a surface receptor for folic acid (Vitamin B9).It was recently reported that FR4 is highly and constitutively expressed on mouse CD4+ CD25+ natural regulatory T cells (Treg).The high expression of this surface marker on Treg can be used in combination with CD4 and CD25 to distinguish Treg from other types of T cells.Since FR4 is a surface marker,this antibody may be used in combination with anti-CD4 and\/or CD25 to sort living T reg cells for functional studies.\u003cbr\u003e\n50μg\u003cbr\u003e\nVerified Reactivity: Mouse\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Rat\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography, and conjugated with FITC under optimal conditions.\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, and protected from prolonged exposure to light.
