{"product_id":"biolegend-516704","title":"Biolegend, 516704, PE anti-human IL-21 Antibody, 100tests","description":"\u003cp\u003eInterleukin 21 (IL-21) is a potent immunomodulatory cytokine primarily produced by NKT cells and CD4 + T cells, particularly the inflammatory Th17 subset. It exerts pleiotropic effects on both innate and adaptive immune responses. These include positive effects such as enhancing proliferation of NK cells and cytotoxic T cells, and inhibitory effects on the antigen-presenting function of dendritic cells. IL-21 also has proapoptotic effects on B cells and NK cells. Recent studies have shown that IL-21 functions as an autocrine cytokine, strongly inducing Th17 differentiation and suppressing Foxp3 expression, making it a potential therapeutic target for treating cancer and inflammatory diseases.\u003cbr\u003e\n100tests\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA)\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography, and conjugated with PE under optimal conditions.\u003cbr\u003e\nConcentration: Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.)\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.
