Description

Label peptides, antibodies and other proteins at primary amines with this benzopyrillium-based Thermo Scientific DyLight orange-emitting specialty dye, which is comparable to Alexa Fluor 594, Alexa Fluor 610, Cy3.5 and Texas Red. DyLight 610-B1 dye has excitation and emission peaks at 610 and 632 nm, respectively.

General features of DyLight orange-emitting specialty dyes:

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

DyLight NIR Dyes are a family of labeling agents that can be used for bright fluorescence detection in cell-based imaging or in vivo imaging applications. NIR dyes can be selected based upon their characteristic excitation and emission properties or relative hydrophilicity and hydrophobicity attributes. Dyes that contain a greater number of negatively charged sulfonates generally will have greater water solubility than dyes with fewer sulfonates. More hydrophobic dyes often provide better cell penetrating ability in vivo, while more hydrophilic dyes have less nonspecific binding potential. Each dye contains an amine-reactive NHS ester for simple modification of antibodies, proteins, peptides or other biomolecules through amide bond formation. NIR dyes are best for imaging through tissues and away from indigenous fluorescent biomolecule interference or quenching. DyLight Near Infrared Dyes represent the largest selection of fluorescent labels that are commercially available.

Criteria to consider when choosing a DyLight NIR Specialty Dye:
• Excitation and emission wavelengths—choose the best dye to match the excitation and emission capabilities of your instrument
• Water solubility—choose a DyLight NIR Dye based on its relative hydrophilicity, which directly correlates to the number of negatively-charged sulfonates it has on its core structure. More hydrophilic dyes are best at maintaining water solubility of a labeled antibody and limiting the nonspecific binding of the conjugate. More hydrophobic dyes often are best at penetrating tissues and cell membranes in vivo, meaning that dyes with fewer sulfonates may work best for some applications.
• DyLight Dye selection—the broad selection of NIR dyes allows a number of candidate dyes to be tested in a given application for optimal performance.
