2,2′-連氮基-雙(3-乙基苯并噻唑啉-6-磺酸)是一種過氧化物酶底物，適用于ELSA（酶聯(lián)免疫吸附分析）規(guī)程。這種底物產生一種綠色可溶性終產物，可在405nm分光光度下讀取。用1%十二烷基硫酸鈉(SDS)可使反應停止。推薦用于ELISA (微孔板)操作，不推薦用于膜應用。游離氯的光譜試劑，酶免顯色底物，過氧化物酶的底物,用于ELISA 步驟，該底物產生一種可溶性的顯綠色的終端產品可在405 nm處光譜讀取。這種反應可用1%SDS終止。

A peroxidase substrate suitable for use in ELISA procedures. This substrate produces a soluble end product that is green in color and can be read spectrophotometrically at 405 nm. The reaction may be stopped with 1% sodium dodecyl sulfate (SDS). Recommended for ELISA (microwell) procedures, but not recommended for membrane applications. A chromogenic substrate for peroxidase. The ABTS-H2O2-peroxidase system in EIA.
