{"product_id":"biolegend-508207","title":"Biolegend, 508207, Alexa Fluor® 647 anti-human IL-1β Antibody, 25tests","description":"\u003cp\u003eIL-1 refers to two proteins, IL-1α and IL-1β which are the products of distinct genes, but which are recognized by the same cell surface receptors. IL-1β is a potent immuno-modulator which mediates a wide range of immune and inflammatory responses including the activation of B and T cells. The JK1B-1 antibody reacts with human interleukin-1β (IL-1β) and baboon IL-1β. The JK1B-1 antibody does not recognize mouse IL-1β or human IL-1α or other cytokines. The JK1B-1 antibody can neutralize the bioactivity of natural or recombinant IL-1β.\u003cbr\u003e\n25tests\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nReported Reactivity: Baboon\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: Recombinant human IL-1 beta\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 Alexa Fluor® 647 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.

Since the pro-form contains the mature sequence, it is believed that the antibody also recognize pro-IL-1beta. Similarly, we believe clone JK1B-1 should also recognize both pro and mature forms of IL-1b. However, this information has not been confirmed with in-house testing data.\u003c\/p\u003e","brand":"Biolegend","offers":[{"title":"Default Title","offer_id":46866458443945,"sku":"508207","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/biolegend-508207","provider":"Iright","version":"1.0","type":"link"}
