| 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 |
L-Kynurenine is a key intermediate in the breakdown pathway of tryptophan. L-Kynurenine is a substrate of kynureninase, KMO, and KAT associated with the suppression of antitumor immune responses. It has been shown to inhibit allogeneic T-cell proliferation and to increase malignant U87 glioma cell invasion into a collagen matrix. L-犬尿氨酸可用作吲哚胺-2,3-双加氧酶分析标准。它还可用作从培养细胞和培养基中提取和定量犬尿氨酸的标准。 L-Kynurenine is a key intermediate in the breakdown pathway of tryptophan.
