In practice, datasets from this type of format are typically interpreted by comparing relative signal, activity, or abundance across matched control and experimental groups rather than relying on a single value in isolation. Careful alignment of sample matrix, incubation window, and calibration strategy is important when comparing results across plates, operators, or study days.\u003c\/p\u003e\n\n\u003ch2\u003eMore details\u003c\/h2\u003e\n\u003cp\u003e\u003ci\u003e Xanthine \u003c\/i\u003eis a purine base that can be found in most animal tissues and fluids. It is a product in the purine degradation pathway, produced by guanine deaminase from guanine, and by xanthine oxidoreductase from hypoxanthine. Xanthine is degraded to uric acid by xanthine oxidase. Clinically, xanthine and its derivatives act on sleep-inducing adenosine receptors as antagonists. Simple, direct, and high-throughput assays for measuring xanthine find wide applications in research and drug discovery. BioAssay Systems xanthine assay kit uses a single Working Reagent that combines the xanthine oxidase reaction and color reaction in one step. The change in color intensity of the reaction product at 570 nm or fluorescence intensity at λex\/em = 530\/585 nm is directly proportional to the xanthine concentration in the sample.\u003c\/p\u003e\n\n\u003ch2\u003eDetection method\u003c\/h2\u003e\n\u003cp\u003eColorimetric (OD 570 nm) or Fluorescent (FL 530\/585 nm).\u003c\/p\u003e\n\n\u003ch2\u003eDetection limit and analytical sensitivity\u003c\/h2\u003e\n\u003cp\u003eReported detection limit: FL 3 µM; OD 10 µM.\u003c\/p\u003e\n\n\u003ch2\u003eProcedures and timing\u003c\/h2\u003e\n\u003cp\u003eStated procedure or timing information: 30 min.\u003c\/p\u003e\n\n\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003ePlate-based quantification and side-by-side group comparison remain central use cases for this assay format.\u003c\/li\u003e\n  \u003cli\u003eThe product notes emphasize multi-sample throughput, making it relevant for screening-oriented and larger batch comparison studies.\u003c\/li\u003e\n  \u003cli\u003eThe description supports intervention-focused study designs in which researchers compare baseline and perturbed conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCommon research applications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eQuantify xanthine in cell lysate, serum by OD570 nm, FL530\/585 nm readout.\u003c\/li\u003e\n  \u003cli\u003eCompare treatment or phenotype groups using matched cell lysate, serum handling.\u003c\/li\u003e\n  \u003cli\u003eMonitor time-course or pre\/post changes in cell lysate, serum across study conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eInterpretation is usually strongest when signal changes are assessed alongside matrix-matched controls, replicate agreement, and the assay's stated analytical window.\u003c\/p\u003e\n\n\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eMatrix composition, background signal, and sample handling can influence apparent response; compare like-with-like whenever possible.\u003c\/li\u003e\n  \u003cli\u003eUse appropriate blanks, controls, and replicate wells to distinguish biological differences from plate, reagent, or handling variability.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- Sources (internal):\n- Product Description column\n- Key Features column\n- More Details column\n- Method \/ Sample Type(s) \/ Assay Time \/ Detection Limit \/ Detection Method columns\n- Procedures column\n- Screening Services column\n--\u003e","brand":"BioAssay Systems","offers":[{"title":"100 Tests","offer_id":53238320955757,"sku":"EXAN-100","price":409.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/EXANfig.jpg?v=1776668362","url":"https:\/\/www.ebiohippo.com\/products\/enzychrom-xanthine-assay-kit-bht15600217","provider":"BioHippo","version":"1.0","type":"link"}
