Sulfo-Cyanine5.5 is a water-soluble, hydrophilic fluorophore which possesses emission in far red area of the spectrum, an analog of Cy5.5®. As other cyanine dyes, sulfo-Cyanine5.5 has an outstanding molar extinction coefficient which gives rise to its bright fluorescence.

The molecule contains four sulfo groups that provide hydrophilicity and negative charge to the fluorophore – this minimizes non-specific binding.

The azide group of sulfo-Cyanine5.5 azide can be conjugated with terminal alkynes in the presence of copper(I) catalyst, or with cycloalkynes in copper free strain promoted reaction.

Sulfo-Cyanine5.5 是一种水溶性、亲水性荧光团,在光谱的远红色区域具有发射,是 Cy5.5® 的类似物。 与其他花青染料一样,sulfo-Cyanine5.5 具有出色的摩尔消光系数,从而产生明亮的荧光。

该分子含有四个磺基,可为荧光团提供亲水性和负电荷 – 这最大限度地减少了非特异性结合。

磺基-Cyanine5.5 叠氮化物的叠氮基团可以在铜(I)催化剂存在下与末端炔烃共轭,或在无铜应变促进反应中与环炔烃共轭。
