| Thermo Scientific DyLight 650 Sulfhydryl-Reactive Dye is a maleimide-activated derivative of high-performance DyLight 650 used to fluorescently label sulfhydryl-containing peptides, proteins, and other biomolecular probes.DyLight 650provides vibrant far-red fluorescence with comparable or improved performance over other dyes, including Alexa Fluor 647 and Cy5 dye, over a broad pH range (pH 4-9). The high water solubility of DyLight Fluors means that a high dye-to-protein ratio can be attained without causing precipitation of the conjugates.yLight 650 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.
