SulfoCy3
菁染料琥珀酰亚胺酯是最常用的脂肪氨基标记试剂，广泛用于蛋白、抗体、核酸及其他生物分子的标记和检测。
通过改变次甲基链的长度, 可改变其荧光发射波长，每增加一个双键，按照Huoffman规则正好红移约100nm。
菁染料Cy3和Cy5已成为基因芯片的首选荧光标记物.
Cy5, Cy5.5和Cy7的吸收在近红外区背景非常低，特别适合于活体小动物体内成像代替放射性元素。

* Measured in phosphate-buffered saline, Mujumdar, R. B., Ernst, L. A., Mujumdar, S. R., Lewis, C. J., and Waggoner, A. S. (1993) Bioconjugate Chem. 4, 105-111.
(Note: The Exitation/Emission wavelength and quantum yield of Cy3 are changed when in a rigid microenvironment, for example in different pH, highly viscous solvents, or when conjugated to biomolecules). Upon attachment to biomolecules (for example oligonucleotides), significant shifts in excitation and emission wavelength have been observed under different pH conditions. Cy3在不同的pH环境中，波长会有较大变化。
