Sulfo-Cyanine5.5 amine potassium 是一种水溶性花青染料，适用于远红/近红外应用，例如体内成像。该染料具有四个磺酸盐基团，使其具有高度亲水性和水溶性。与其他花青一样，sulfo-Cyanine5.5 具有出色的消光系数，使其成为远红区域的明亮荧光标记。这是一种含胺荧光染料。胺基团通过有利于缀合的相对较长的连接体与荧光团分开。脂肪族伯胺基团可以与各种亲电子试剂（活化酯、环氧化物等）偶联，也可用于酶促氨基转移标记。

Sulfo-Cyanine5.5 amine potassium is a water-soluble cyanine dye suitable for far-red/near-infrared applications such as in vivo imaging. The dye has four sulfonate groups, making it highly hydrophilic and water-soluble. Like other cyanines, sulfo-Cyanine5.5 has an excellent extinction coefficient, making it a bright fluorescent marker in the far-red region. This is an amine-containing fluorescent dye. The amine group is separated from the fluorophore by a relatively long linker that facilitates conjugation. Aliphatic primary amine groups can be coupled with various electrophiles (activated esters, epoxides, etc.) and can also be used for enzymatic transamination labeling.
