Pyrene maleimide,芘-馬來酰亞胺
目前Cyanine系列染料以兩種異構(gòu)體的形式存在，一種是非磺化花青素（non-sulfonated cyanines），一種是磺化花青素（sulfonatedcyanine）。兩者的光譜性質(zhì)幾乎*，因此大部分應(yīng)用可相互替換。

產(chǎn)品介紹

Pyrene maleimide

Pyrene is a fluorescent hydrocarbon which emits in blue region. This is a maleimide derivative of pyrenebutyric acid which reacts with thiols.

Pyrene is a useful proximity probe because two pyrene residues close to each other exhibit strong excimer fluorescence.
