亚甲基蓝 三水合物
作者：德尔塔 日期：2022-01-09
Methylene Blue acts as a GCS (guanylyl cyclase) inhibitor, biological stain and redox indicator. Methylene Blue inhibits tau filament formation. Additionally, Methylene Blue is also reported to inhibit NOSs (nitric oxide synthase). Methylene Blue is widely used to inhibit cGMP-mediated processes. Methylene Blue has been observed to dose-dependently induce cytotoxicity in U-373 MG human astrocytoma and SK-N-MC human neuroblastoma cells. Furthermore Methylene Blue is reported to bind to the M2 subtype of muscarinic receptors in rat cardiac myocytes, and thus exhibit antimuscarinic effects on IK, ACh and ICa. Methylene Blue has also been reported to inhibit endothelium-dependent relaxation of isolated blood vessels.An inhibitor of cGMP-mediated processes and guanylyl cyclase, a useful stain, and a redox indicator 安全信息 标识符号 GHS07

甲基红钠盐
作者：德尔塔 日期：2022-01-09
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. 属性 产品名称 甲基红钠盐 产品名称 Methyl Red sodium salt 别名 酸性红2；2-[4-(二甲基氨基)苯基偶氮]苯甲酸钠盐；甲基红钠;甲基红，钠；甲基红 钠盐；4-二甲氨基偶氮苯-2′-羧酸 钠盐 英文别名 Methyl Red, sodium sal
