产品简介

Pyrene maleimide,芘-马来酰亚胺
目前Cyanine系列染料以两种异构体的形式存在，一种是非磺化花青素（non-sulfonated cyanines），一种是磺化花青素（sulfonatedcyanine）。两者的光谱性质几乎*，因此大部分应用可相互替换。

产品介绍

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.
