Thermo Scientific™ DyLight™ 747-B4 NHS Ester
Thermo Scientific DyLight near-infrared specialty dyes, comparable to Alexa Fluor and IRDye NIR dyes, can be used to label antibodies, peptides, and other proteins at primary amines. DyLight 747-B4 dye has a structure based on the benzopyrillium core, with 4 sulfonate. It has excitation and emission peaks at 748 and 775 nm, respectively (in ethanol).
Features
- Large selection—the largest family of dyes available for NIR fluorescence applications
- NHS ester reactive group—allows immediate labeling of antibodies, proteins, peptides and other amine-containing molecules through amide bond formation
- Broad spectrum of water solubilities—choose from hydrophilic to hydrophobic dyes to optimize the right dye label for the best performance in a given application
- NIR dyes avoid background interference—DyLight NIR Dyes avoid fluorescence interference or quenching effects from biomolecules present in samples
- Excellent signal penetration through cells and tissues—DyLight NIR Dyes provide the optimal window for excitation and emission for in vivo imaging applications
