Cyanine7.5 Maleimide (CAS: 2270866-73-2)
Cyanine7.5 maleimide is a near-infrared (NIR) dye that labels thiol groups in biomolecules. Its maleimide group binds specifically to sulfhydryl groups, allowing easy conjugation with proteins, peptides, and other thiol-containing molecules. With strong NIR fluorescence, it works well for in vivo imaging and deep tissue applications with low background noise.
Key Features
- Spectral Properties: Excites at 788 nm and emits at 808 nm, providing bright NIR fluorescence.
- Thiol Specificity: The maleimide group binds selectively to thiol groups, making it perfect for labeling cysteine residues in proteins.
Cyanine7.5 maleimide Applications
- Protein Labeling: Adds NIR fluorescent tags to proteins for tracking and visualization.
- In Vivo Imaging: Ideal for non-invasive imaging with deep tissue penetration and minimal background signals.
- Bioconjugation: Enables the attachment of fluorescent dyes to biomolecules for molecular biology, biochemistry, and diagnostics.
Storage and Handling
- Storage: Keep at -20°C in the dark to ensure stability.
- Precautions: Protect from light and moisture to avoid degradation.
Cyanine7.5 maleimide provides an efficient and reliable solution for NIR fluorescent labeling in research and imaging.
