生物活性	Bromothymol Blue is a pH indicator.
性状	Solid
体外研究(In Vitro)	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 Bromothymol Blue 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, ther

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
