Sulfo-Cyanine7.5 is a near infrared water soluble and hydrophilic dye for the NIR imaging applications. The structure and spectra of the dye resemble indocyanine green (ICG) that has been approved for use in humans for years. However, unlike ICG, sulfo-Cyanine7.5 contains a trimethylene bridge that increases its quantum yield compared to ICG, and also has a linker arm for its attachment to proteins, peptides, and other molecules. This derivative is an NHS ester for the modification of amine groups.
Sulfo-Cy7.5 是一种用于近红外成像应用的近红外水溶性亲水染料。 该染料的结构和光谱类似于已被批准用于人类多年的吲哚菁绿 (ICG)。 然而，与 ICG 不同，磺基-Cy7.5 含有一个三亚甲基桥，与 ICG 相比，它增加了其量子产率，并且还具有一个连接臂，用于连接蛋白质、肽和其他分子。 该衍生物是用于修饰胺基的 NHS 酯。
