Thermo Scientific DyLight 680 Amine-Reactive Dye is an NHS ester-activated derivative of high-performance DyLight 680 used to fluorescently label antibodies and other proteins that are then used as molecular probes for cellular imaging and other fluorescence detection methods.

DyLight 680 produces near-infrared (IR) fluorescence that replaces other near-IR dyes, including Cy5.5 and Alexa Fluor 680, and is ideal for multi-color applications.The high water solubility of DyLight Fluors means that a high dye-to-protein ratio can be attained without causing precipitation of the conjugates. DyLight 680 Amine-Reactive Dye is available as a stand-alone reagent or as part of two antibody labeling kit sizes.

Highlights:

• High performance – DyLight 680 fluoresces brighter than Alexa Fluor 680 and Cy5.5
• Specific – NHS ester-activated dye labels proteins and other molecules at primary amines (-NH2)
• Convenient kit sizes – standard and microscale sizes are offered to match your experimental needs
• Optimized procedure – following the standard protocol results in antibodies with excellent dye:protein ratios and recovery rates for optimum activity and fluorescence labeling
