{"product_id":"biolegend-509502","title":"Biolegend, 509502, Biotin anti-human IL-1 RA Antibody, 500μg","description":"\u003cp\u003eInterleukin-1 receptor antagonist (IL-1RA) is composed of three isoforms, one secreted (sIL-1Rα\/IL-1Rα1), two intracellular (IL-1Rα2\/IL-1Rα3) and produced by monocytes, tissue macrophages, Langerhans cells, dendritic cells, T and B cells, natural killer (NK) cells, large granular lymphocytes (LGL), vascular endothelium, smooth muscle, fibroblasts, thymic epithelia, astrocytes, microglia, glioma cells, keratinocytes, and chondrocytes. It is upregulated by IL-1β, IL-4, IL-6 and downregulated by glucocorticoids. The Poly5095 polyclonal antibody reacts with human interleukin-1 receptor antagonist (IL-1RA).\u003cbr\u003e\n500μg\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nAntibody Type: Polyclonal\u003cbr\u003e\nHost Species: Rabbit\u003cbr\u003e\nImmunogen: Recombinant human IL-1 receptor antagonist\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 biotin 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.
