一般說明

ABTS主要可用于ELISA(酶联免疫吸附测定)实验中。
ABTS,2,2′-连氮基-双(3-乙基苯并噻唑啉-6-磺酸)是一种生色底物,可用于:
  • 与漆酶或胆红素氧化酶的反应
  • 与过氧化物酶的反应:(例如HRP)。ABTS与过氧化氢结合
在过氧化氢的存在下,ABTS的过氧化物酶反应可产生绿色的可溶终产物,该终产物可以在405nm处用分光光度法进行读取。用1%十二烷基硫酸钠(SDS)可使反应停止。
ABTS,2,2′-连氮基-双(3-乙基苯并噻唑啉-6-磺酸)二铵盐对光敏感,并且是一种水溶性化合物

應用

  • 2,2′-连氮基-双(3-乙基苯并噻唑啉-6-磺酸)二铵盐(ABTS)已用作ELISA(酶联免疫吸附分析)的底物。
  • ABTS还可用于测定包括血清在内的不同溶液中的葡萄糖浓度。
  • 食品工业使用ABTS来测定不同食品中的抗氧化能力。
  • 由于它比TMB和OPD底物更不易被氧化,因此ABTS对ELISA应用的敏感性较低。因此,在背景结果较大的情况下,ABTS相较于TMB和OPD更具优势
  • 推荐用于ELISA (微孔板)操作,不推荐用于膜应用。
2,2′-联氮基-双3-乙基苯并噻唑啉-6-磺酸)是一种过氧化物酶底物,适用于ELISA程序。该底物产生一种可溶性最终产物,其颜色为绿色,可在405nm分光光度法下读取。用1%十二烷基硫酸钠(SDS)可使反应停止。 推荐用于ELISA (微孔)程序,不推荐用于膜应用。

商品

Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures. These substrate systems produce an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually.

实验方案

This procedure may be used for all Alcohol Oxidase products. The continuous spectrophotometric rate determination (A405, Light path = 1 cm) is based on the following reactions.
