Cyanine3 dye azide for Click Chemistry, an analog of Cy3® azide. Cy3® is one of the most broadly used fluorophores which can be detected by various fluorometers, imagers, and microscopes. Due to inherently high extinction coefficient, Cyanine3 is also easily detected by naked eye on gels, and in solution. This is non-sulfonated dye which requires organic co-solvent (DMF, DMSO, or other) for efficient labeling in water. Water-soluble version of this reagent is alsoavailable.

疊氮(azide)是常用生物標(biāo)記基團(tuán)。通過點(diǎn)擊化學(xué)反應(yīng)(click chemistry),疊氮可以和一系列炔烴(alkyne)或環(huán)炔烴(strained alkyne)生成穩(wěn)定的生物鏈接(bioconjugate)。點(diǎn)擊化學(xué)反應(yīng)效率很高,可在水相中(也可有機(jī)相)快速定量完成(幾乎100%產(chǎn)率),即使在低濃度(μM)和低溫(4oC)下也可完成。點(diǎn)擊化學(xué)反應(yīng)技術(shù)發(fā)展很成熟,各種相關(guān)試劑商業(yè)可得,各種生物標(biāo)記應(yīng)用。

Cy3標(biāo)記后的產(chǎn)物Ex/Em是554/566nm。和它具有相似熒光特性的染料包括TAMRA,Alexa Fluor 555,DyLight 550,BODIPY TMR-X等。
