广义的Cy染料是一种结构和应用非常广泛的一大类荧光化合物。在这里我们主要讨论用于生物标记的Cy染料，包括Cy3，Cy3.5，Cy5，Cy5.5，Cy7和Cy7.5。所有的这些染料都是上世纪70年从染料ICG（Indocyanine Green）衍生出来的，和ICG一样它们都有两个对称的indolenine发色团。

2022年4月2日 · cy系列荧光染料:也被称为菁染料或花青素系列荧光染料，是一种具有多聚次甲基桥链化学结构特点的合成荧光染料。cy染料(cy3，cy3.5，cy5，cy5.5, cy7, cy7.5)的次甲基桥链（1-7个次甲基）两端常常连着两个氮原子，其中一个氮原子带正电，从而形成具有离域正电荷 ...

DBCO-Cy3 (DBCO-Sulfo-Cy3) is the derivative of Cyanine3 fluorophore, a pH insensitive from pH (4-10) orange fluorescent dye with excitation maximum 555 nm and emission maximum of 580nm. DBCO-Cy3 has fast reaction kinetics and good stability, and is productive to use in many standard fluorescent instrumentations.
