Overview:
Cyanine7 Azide (CAS Number: 1557149-65-1) is a near-infrared fluorescent dye for Click Chemistry labeling, serving as an analog of Cy7® azide. It efficiently incorporates Cyanine7 into alkynylated biomolecules through Click Chemistry and is also useful for post-synthetic oligonucleotide modification, offering versatile labeling options.
Key Features:
- Excitation/Emission: 750 nm / 773 nm (near-infrared range)
- Cyclohexane-Bridged Chain: Increases quantum yield by 20%, delivering brighter fluorescence compared to non-bridged structures.
- Azide Group: Efficiently links to alkynylated biomolecules via Click Chemistry for fast, precise labeling.
Cyanine7 Azide Applications:
- Click Chemistry Labeling: Labels alkynylated biomolecules quickly and efficiently using azide-alkyne cycloaddition.
- Oligonucleotide Modification: Modifies oligonucleotides post-synthetically, making it ideal for nucleic acid labeling.
- In Vivo Imaging: Near-infrared fluorescence is perfect for deep-tissue imaging with reduced background interference.
- Fluorescence Microscopy: Provides bright, stable signals for clear imaging in biological research.
Benefits:
- Stronger Fluorescence: The cyclohexane-bridged chain boosts quantum yield by 20%.
- Enhanced Imaging: Near-infrared emission reduces background noise, ideal for in vivo imaging.
- Versatile Labeling: Effectively labels a wide range of biomolecules, including oligonucleotides, using Click Chemistry.
