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\u003cem\u003eINDOLE\u003c\/em\u003eis the primary product of tryptophan breakdown by tryptophanase. The indole test is commonly performed on bacteria to classify them on their ability to break down tryptophan to indole. BioAssay Systems indole assay kit is based on a modified version of Ehlrich’s and Kovac’s reagents, which reacts with indole to produce a colored compound at 565 nm. The intensity of this colored compound is directly proportional to the indole 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: 3 µM.\u003c\/p\u003e\n\n\u003ch2\u003eProcedures and timing\u003c\/h2\u003e\n\u003cp\u003eStated procedure or timing information: Under 5 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 description supports intervention-focused study designs in which researchers compare baseline and perturbed conditions.\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 indole in bacterial growth media by OD565 nm readout.\u003c\/li\u003e\n  \u003cli\u003eCompare treatment or phenotype groups using matched bacterial growth media handling.\u003c\/li\u003e\n  \u003cli\u003eMonitor time-course or pre\/post changes in bacterial growth 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":53238312829293,"sku":"DIND-100","price":239.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/DINDfig.jpg?v=1776668350","url":"https:\/\/www.ebiohippo.com\/products\/quantichrom-indole-assay-kit-bht15600070","provider":"BioHippo","version":"1.0","type":"link"}
