备注 大客户需求,外观必须白色,质控外观要保持白色。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

Trolox is an antioxidant derived from water-soluble vitamin E, with oxygen quenching activity. The activity of Trolox ranges between ferulic acid and p-coumaric acid. Studies show that lipid peroxidation, cytotoxicity, and apoptosis induced by cytochrome P450 2E1 in Hep G2 cells is blocked in the presence of Trolox. It has been observed that Trolox can quench free radicals and inhibit methylmercury (MeHg)-induced reactive oxygen species (ROS) generation in C6 glial cells. In addition, Trolox has demonstrated the ability to reduce cytotoxicity of Microcystis aerμginosa and microcystin-LR in Artemia franciscana nauplii.?()-6-hydroxy -2,5,7,8- tetramethylchroman -2- carboxylic acid (Trolox) exhibits free radical scavenging and antioxidant activities.

An antioxidant derived from water-soluble vitamin E ()-6- hydroxy -2,5,7,8- tetramethylchroman -2- carboxylic acid (Trolox) has been used in the equivalent antioxidant test (TEAC) of 6-hydroxy -2,5,7,8- tetramethylchroman -2- carboxylic acid to determine different fruits.
