产品简介

Cy5.5 Dyes,Cy5.5菁染料,近红外荧光染料
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

Cy5.5 Dyes

Cy5.5 dyes are among the most widely used fluorescent labels for preparing NIR fluorescent bioconjugates. Cy5.5 conjugates are very bright, photostable, and pH insensitive and produce minimal autofluorescence of biological specimens in this region of the spectrum. With a peak excitation at 678 nm and a maximum emission at 694 nm, Cy5.5 is spectrally almost identical to other near-IR dyes, including DyeLight 680™, IRDye™ 680 dye, and Alexa Fluor™ 680, and is ideal for multi-color applications.
 
This sulfonated dye is also known as sulfo-Cyanine5.5 NHS ester. Cy®Dye is a trademark of GE Healthcare.
