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\u003eGLUTAMINASE\u003c\/i\u003e(EC 3.5.1.2) is a key enzyme in the metabolism of glutamine. Glutamine is an important amino acid in the metabolism of cancer cells, and increased glutaminolysis has been linked to cancer. BioAssay Systems’ DGLN-100 Kit provides a convenient fluorimetric method to measure glutaminase activity in biological samples. In this assay, o-phthalaldehyde reacts with liberated ammonia where the increase in fluorescence at λex\/em = 415\/475 nm is directly proportional to enzyme activity.\u003c\/p\u003e\n\n\u003ch2\u003eDetection method\u003c\/h2\u003e\n\u003cp\u003eFluorescent (FL 415\/475 nm).\u003c\/p\u003e\n\n\u003ch2\u003eDetection limit and analytical sensitivity\u003c\/h2\u003e\n\u003cp\u003eReported detection limit: 0.66 U\/L.\u003c\/p\u003e\n\n\u003ch2\u003eProcedures and timing\u003c\/h2\u003e\n\u003cp\u003eStated procedure or timing information: 50 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\u003eShort assay timing and plate compatibility support time-course or repeated-measure collection plans when handling is kept consistent.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCommon research applications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eQuantify glutaminase in biological Samples, Purified Enzyme by FL415\/475 nm readout.\u003c\/li\u003e\n  \u003cli\u003eCompare treatment or phenotype groups using matched biological Samples, Purified Enzyme handling.\u003c\/li\u003e\n  \u003cli\u003eMonitor time-course or pre\/post changes in biological Samples, Purified Enzyme 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 in 96-well plate","offer_id":53238317547885,"sku":"DGLN-100","price":409.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/DGLNfig.jpg?v=1776668352","url":"https:\/\/www.ebiohippo.com\/products\/quantifluo-glutaminase-assay-kit-bht15600047","provider":"BioHippo","version":"1.0","type":"link"}
