{"product_id":"new-product-132393","title":"Rat IL-21(Interleukin 21) ELISA Kit","description":"The RAT IL-21 (Interleukin 21) ELISA Kit is a highly reliable and efficient tool designed for the quantitative measurement of Interleukin 21 in rat samples. Interleukin 21 is a cytokine that plays a crucial role in the regulation of immune responses, particularly in the development and function of T cells and B cells. This ELISA kit provides researchers with a precise and accurate method to assess IL-21 levels in various biological samples, enabling a deeper understanding of immune system dynamics and potential therapeutic targets.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThis ELISA kit offers exceptional sensitivity and specificity, ensuring accurate and reproducible results. It utilizes a sandwich enzyme-linked immunosorbent assay technique, where a monoclonal antibody specific to rat IL-21 is pre-coated onto a microplate. The IL-21 present in the sample binds to the immobilized antibody, while any unbound substances are washed away. A biotin-conjugated polyclonal antibody specific to IL-21 is then added, forming a sandwich complex. This complex is further amplified by the addition of an enzyme-conjugated streptavidin, followed by the addition of a substrate solution that generates a color reaction. The intensity of the color is directly proportional to the concentration of IL-21 in the sample, which can be measured spectrophotometrically.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThis ELISA kit is user-friendly and provides a wide dynamic range, allowing for the detection of IL-21 in a variety of sample types, including serum, plasma, and cell culture supernatants. It offers excellent precision with low intra-assay and inter-assay coefficients of variation, ensuring reliable and reproducible results. The kit includes all necessary components, including pre-coated microplates, antibodies, enzyme conjugates, and buffers, providing convenience and ease of use. With its high sensitivity, specificity, and accuracy, the RAT IL-21 ELISA Kit is an indispensable tool for researchers studying immune system regulation, inflammation, and potential therapeutic interventions.","brand":"Elabscience","offers":[{"title":"96T","offer_id":47626378477848,"sku":"E-EL-R0568","price":609.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/elisa-1_98791d57-27e7-4e67-9de5-7cbac95727e5.jpg?v=1706824099","url":"https:\/\/danabiosci.com\/products\/new-product-132393","provider":"Dana Bioscience","version":"1.0","type":"link"}
