Sulfo-Cyanine5.5 (analog of Cy5.5®) is a water-soluble, far red emitting fluorophore. Due to four sulfo-groups, the dye possesses negative charge in neutral pH, and very high hydrophilicity.
As a cyanine dye, sulfo-Cyanine5.5 shows very low dependence of the fluorescence on pH, and very high extinction coefficient.
Sulfo-Cyanine5.5（Cy5.5® 的类似物）是一种水溶性、发射远红光的荧光团。 由于四个磺基，该染料在中性pH下具有负电荷，并且具有非常高的亲水性。
作为一种花青染料，sulfo-Cyanine5.5 的荧光对 pH 的依赖性非常低，消光系数非常高。
