Sulfo-Cyanine7 carboxylic acid is non-reactive water soluble near infrared dye.

The reagent is useful as a fluorescent marker in NIR range when attachment to other molecules is not desired. It has high hydrophilicity and aqueous solubility, improved quantum yield in NIR range, and very high molar extinction coefficient.

This reagent contains free carboxylic acid function. Pre-activated activated ester – sulfo-Cyanine7 NHS ester is also available.

Sulfo-Cyanine7 羧酸是非反应性水溶性近红外染料。

当不需要与其他分子结合时,该试剂可用作 NIR 范围内的荧光标记。 它具有高亲水性和水溶性,在近红外范围内提高了量子产率,并且具有非常高的摩尔消光系数。

该试剂含有游离羧酸功能。 也可提供预活化的活化酯 – 磺基花青7 NHS 酯。

Sulfo-Cyanine7.5 azide

Sulfo-Cyanine7.5 is a very hydrophilic and water soluble dye for the near infrared region. The absorption and emission spectra of the dye are similar to indocyanine green (ICG), but sulfo-Cyanine7.5 has a much higher fluorescence quantum yield. The dye is a great choice for near infrared in vivo imaging. This is an azide for Click chemistry.

Sulfo-Cyanine7.5 是一种用于近红外区域的亲水性和水溶性染料。 该染料的吸收和发射光谱与吲哚菁绿 (ICG) 相似,但磺基-Cyanine7.5 具有更高的荧光量子产率。 该染料是近红外体内成像的绝佳选择。 这是点击化学的叠氮化物。
