生化机理：一氧化氮（NO）的高灵敏度，特异性荧光检测器。直到与NO反应生成高度荧光的三唑并荧光素（DAF-2T）为止，基本上是无荧光的。

储存温度：-20°C储存

运输条件：超低温冰袋运输

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：DAF-2 is a sensitive and specific fluorescent indicator for the direct detection of nitric oxide (NO) in vitro. In the presence of oxygen, the relatively non-fluorescent DAF-2 reacts rapidly with NO to yield the highly fluorescent triazolofluorescein compound. DAF-2 can detect NO under neutral conditions (detection limit = 5 nM).A sensitive and specific fluorescent indicator for the direct detection of nitric oxide (NO) in vitro.
