一般描述

<甲基红溶液是一种偶氮染料，当 pH 值低于 4.4 时会变成红色（黄色 pH 值 6.2，橙色 pH 值 4.4-6.2）。某些细菌可利用葡萄糖形成大量的酸，从而导致培养基pH值明显下降。其它物种不产生或只产生较少的游离酸。这种差异可通过甲基红观察到。 该测试用于区分肠道细菌。

应用

甲基红溶液是一种 pH 指示剂染料，推荐用于检测各种样品中葡萄糖发酵的产酸细菌，如肠杆菌科细菌。

Asymmetric dye clusters with a single fluorophore (Cy3) and multiple quenchers (4'-methylthioazobenzene-4-carboxylate, methyl red, and 4'-dimethylamino-2-nitroazobenzene-4-carboxylate) were prepared. The dye and one-to-five quenchers were tethered through D-threoninol to opposite strands of a DNA duplex. NMR analysis revealed that the clusters
