| Thermo Scientific DyLight 680 Sulfhydryl-Reactive Dye is a maleimide-activated derivative of high-performance DyLight 680 used to fluorescently label sulfhydryl-containing peptides, proteins and other biomolecular probes.DyLight 680produces near-infrared (IR) fluorescence that replaces other near-IR dyes, including Cy5.5™ dye 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 Sulfhydryl-Reactive Dye is activated with a maleic acid imide (maleimide) moiety to form a reactive alkylation reagent. Labeling occurs through reaction of the maleimide-activated dye with reduced sulfhydryl groups (-SH) to form stable thioether bonds. Maleimides are specific for sulfhydryl groups between pH 6.5-7.5.
