用途

溴百里酚蓝是弱酸和弱碱的pH指示剂。染料和代谢产物。

生物活性

Bromothymol Blue 是一种 pH 指示剂，是测定弱酸弱碱时使用的一种指示剂，其酸性时为黄色，碱性时为蓝色。

体外研究

A first characterization and comparison is done by developing an easy and direct measurement method based on a pH indicator system using Bromothymol Blue (BTB) as the indicator and potassium phosphate as the buffer. A pH-shift assay is developed on the basis of BTB as the pH indicator and potassium phosphate as the buffer component. Three pH indicators are tested for the direct determination of 2- 2-keto-L-gulonic acid (2-KLG) production on a plate. The results show that Bromothymol Blue is superior to the other two indicators in terms of the obvious color change and a suitable pH range (blue to yellow at pH 6.5-7.5). Upon the addition of a Bromothymol Blue solution (0.1%, w/v) to an agar plate, zones surrounding colonies of K. vulgare 07 mutants change their color from blue to yellow because K. vulgare 07 mutants release 2-KLG on agar plates, thereby acidifying surrounding areas around colonies.
