英文名称：Methyl Red sodium salt

生化机理：Methyl Red is a pH indicator and it changes color at a pH of 5.5.pH indicator turning red under pH 4.4, yellow over pH 6.2, and orange in between those values. Azo dye used in microbiology to identify bacteria that produce stable acids through mixed acid fermentation of glucose.

应用：酸碱指示剂，pH变色范围4.4(红)～6.2(黄)。氧化还原指示剂。用于硫酸铈滴定亚铁离子。 Methyl red sodium salt is primarily used in microbiology in order to identify bacteria such as Enterobacter agglomerans in dye-contaminated sludge.

备注：如果有可能，您尽量在使用的当天配置溶液，并在当天使用完它。但是，如果您需要预先配制储备溶液，我们建议您将溶液等份保存在-20°C的密封小瓶中。通常，它们最多可以使用一个月。在使用前和打开样品瓶之前，我们建议您让您的产品在室温下平衡至少1小时。需要更多关于溶解度，用法和处理的建议吗？请访问我们的常见问题（FAQ）页面以获取更多详细信息。

产品介绍：溶于水和乙醇。最大吸收波长437nm。 Methyl Red is an azo dye that indicates the presence of acid in the culture medium, which is formed due to fermentation of sμgar by bacteria. This red dye is reduced to orange color in the presence of acid. Methyl Red has been used as a part of IMViC (indole, methyl red, Voges-Proskauer and citrate utilization or catalase production test). IMViC is a biochemical test performed to differentiate among the coliforms, specifically Escherichia coli and Enterobacter aerogene. Methyl red sodium salt is the sodium salt of methyl red synthetic dye, which belongs to the azo group of dyes. 酸碱指示剂，pH变色范围4.4(红)～6.2(黄)。氧化还原指示剂。用于硫酸铈滴定亚铁离子。 Methyl red sodium salt is primarily used in microbiology in order to identify bacteria such as Enterobacter agglomerans in dye-contaminated sludge.Methyl Red is an azo dye that indicates the presence of acid in the culture medium, which is formed due to fermentation of sugar by bacteria.
