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 FUMARATE\u003c\/i\u003e, or Fumaric Acid, is one of the key components in the TCA cycle and is used by cells to form ATP. Human skin when exposed to sunlight will naturally produce fumaric acid. Fumarate is used as an additive by the food and beverage industries. Fumaric acid esters are also used to treat psoriasis. Increased urinary fumarate may be due to impaired Krebs cycle function, a defect in the enzyme fumarase, or mitochondrial function. BioAssay Systems fumarate assay kit is based on fumarase-catalyzed hydration of fumarate to malate. The malate is then oxidized by malate dehydrogenase generating NADH which reduces a formazan (MTT) dye. The intensity of the product color, measured at 565 nm is proportional to the fumarate concentration in the sample.\u003c\/p\u003e\n\n\u003ch2\u003eDetection method\u003c\/h2\u003e\n\u003cp\u003eColorimetric (OD 565 nm).\u003c\/p\u003e\n\n\u003ch2\u003eDetection limit and analytical sensitivity\u003c\/h2\u003e\n\u003cp\u003eReported detection limit: 5 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 fumarate in food, beverage (cell lysate, tissue by OD565 nm readout.\u003c\/li\u003e\n  \u003cli\u003eCompare treatment or phenotype groups using matched food, beverage (cell lysate, tissue handling.\u003c\/li\u003e\n  \u003cli\u003eMonitor time-course or pre\/post changes in food, beverage (cell lysate, tissue 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":53238318301549,"sku":"EFUM-100","price":479.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/EFUMfig.jpg?v=1776668358","url":"https:\/\/www.ebiohippo.com\/products\/enzychrom-fumarate-assay-kit-bht15600158","provider":"BioHippo","version":"1.0","type":"link"}
