Thermo Scientific™ DyLight™ 780-B1 NHS Ester

Thermo Scientific™ DyLight™ 780-B1 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 780-B1 dye has a structure based on the benzopyrillium core, with 1 sulfonate. It has excitation and emission peaks at 783 and 799 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
