{"product_id":"biolegend-513009","title":"Biolegend, 513009, Purified anti-human IL-21 (Maxpar® Ready) Antibody, 100μg","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\n100μg\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nReported Reactivity: Rhesus\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: Recombinant full length human IL-21\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and EDTA.\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography.\u003cbr\u003e\nConcentration: 1.0 mg\/ml\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C.\u003cbr\u003e\nApplication: ELISA Capture - Quality tested CyTOF® - Verified\u003cbr\u003e\nRecommended Usage: This product is suitable for use with the Maxpar® Metal Labeling Kits.

While it is likely that this will work in majority of the situations, it is best to use the non-EDTA formulated version of the same clone for flow cytometry testing. The presence of EDTA in some situations might negatively affect staining.\u003cbr\u003e\nQ: I am having difficulty observing a signal after conjugating a metal tag to your Maxpar® antibody. Please help troubleshoot.\u003cbr\u003e\nA: We only supply the antibody and not test that in house.

The regular purified format clones are formulated in solution that does not contain any EDTA. Both formulations are however without any extra carrier proteins.\u003c\/p\u003e","brand":"Biolegend","offers":[{"title":"Default Title","offer_id":46862385381545,"sku":"513009","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/biolegend-513009","provider":"Iright","version":"1.0","type":"link"}
