Sulfo-Cyanine5.5 (Cy5.5) alkyne，Cy5.5 类似物，是一种炔基修饰的近红外 (NIR) 荧光染料 (Ex=678 nm, Em=694 nm)。 Sulfo-Cyanine5.5 alkyne 可与叠氮化物反应，用于点击化学标记。 Extinction Coefficient Excitation Maximum: 209000;Fluorescence Quantum Yield: 0.2 Cy5.5 alkyne is a cynaine derivative containing an alkyne group, which enables Click Chemistry to attach deeply colored and photostable Cyanine5.5 fluorophore to various azide-bearing molecules. Cyanine5.5 is a popular fluorophore that has been widely used for various applications including intact organism imaging. Product description： Far red / near-infrared dye alkyne for сlick сhemistry labeling. Cyanine5.5 is an analog of Cy5.5, a popular fluorophore widely used for various applications, including intact organism imaging. This reagent can be conjugated with azido groups under mild copper-catalyzed сlick сhemistry conditions. This reagent is soluble in organic solvents, but mixtures of water with a small percent of DMSO can be used for efficient conjugation. Cyanine5.5 alkyne can also be used for the labeling of small molecules with this far red/NIR dye.
