{"product_id":"biolegend-131908","title":"Biolegend, 131908, PE\/Cyanine5 anti-mouse IL-21R Antibody, 100μg","description":"\u003cp\u003eThe IL-21R is a member of the cytokine receptor family that closely resembles IL-2R beta and IL-4R alpha. IL-21R is expressed by all mature lymphocytes and up-regulated after B and\/or T cell activation, with the highest expression by activated B cells. A functional IL-21R consists of the IL-21R subunit and the commone gamma-chaiin. Upon binding to IL-21, it activates Jak-1, Jak-3, STAT1, STAT3 and STAT 5 transduction pathway.\u003cbr\u003e\n100μg\u003cbr\u003e\nVerified Reactivity: Mouse\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Rat\u003cbr\u003e\nImmunogen: Rat YB2\/0 hybridoma transfectant cell line expressing truncated IL-21R\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 PE\/Cyanine5 under optimal conditions.\u003cbr\u003e\nConcentration: 0.2 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.
