Cyanine3 dye azide可以用于点击化学,是Cy3® azide的类似物。Cy3®是广泛使用的荧光素之一,因为它可以被各种不同的荧光计、成像仪和显微镜检测到。因其固有的高的消光系数,在溶解状态,肉眼也可以很容易观察到在凝胶上的Cyanine3。本产品是非磺化的,需要如DMF,DMSO或其他有机溶剂共溶剂来有效的在水中进行标记。水溶的该染料产品:Sulfo-Cyanine3 azide。 该产品有两种形式可供选择:粉剂和在我们的推荐手册中提到的溶解在DMSO(浓度:10mM)中的即用型溶液形式。 Cyanine3荧光素与Cy3®特性相同,类似与Alexa Fluor 546, and DyLight 549。
