Cyanine7.5 is a NIR dye with long-wave infrared fluorescence. This derivative is azide for click chemistry.
Can be used for the construction of various labeled biomolecules containing Cyanine7.5, near-infrared fluorescent dye, and an improved analog of Cy7.5®. These conjugates can take advantage of NIR tissue transparency when used for in vivo imaging. This fluorophore is also useful for other fluorescent applications, especially requiring low fluorescent background.
Azide is available as a DMSO solution, ready for general click chemistry labeling protocol, or in solid form for custom labeling applications.
Structure features a rigid bridged polymethine chain to increase quantum yield by 20%, allowing for a brighter signal.
