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 ISOCITRATE DEHYDROGENASE \u003c\/i\u003e(IDH) is an enzyme that catalyzes the interconversion of isocitrate and a-ketoglutarate. There are three IDH isoforms: IDH3 uses the cofactor NAD\u003csup\u003e+\u003c\/sup\u003eand catalyzes the third step in the citric acid cycle, while IDH1 and IDH2 use the cofactor NADP\u003csup\u003e+\u003c\/sup\u003eand catalyze the same reaction outside the citric acid cycle. This kit measures the activity of the NADP\u003csup\u003e+\u003c\/sup\u003eisoforms. Mutations in IDH1 and IDH2 have been linked with various brain tumors and acute myeloid leukemia. BioAssay Systems’ non-radioactive, colorimetric IDH assay is based on the reduction of the tetrazolium salt MTT in an NADPH-coupled enzymatic reaction to a reduced form of MTT which exhibits an absorption maximum at 565 nm. The increase in absorbance at 565 nm is directly proportional to the enzyme activity.\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: 0.1 U\/L.\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 isocitrate dehydrogenase in plasma, serum, tissue and culture media by OD565 nm readout.\u003c\/li\u003e\n  \u003cli\u003eCompare treatment or phenotype groups using matched plasma, serum, tissue and culture media handling.\u003c\/li\u003e\n  \u003cli\u003eMonitor time-course or pre\/post changes in plasma, serum, tissue and culture media 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":53238314041709,"sku":"DIDH-100","price":489.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/DIDHfig.jpg?v=1776668351","url":"https:\/\/www.ebiohippo.com\/products\/quantichrom-isocitrate-dehydrogenase-assay-kit-bht15600061","provider":"BioHippo","version":"1.0","type":"link"}
