| Thermo Scientific DyLight 405 Sulfhydryl-Reactive Dye is a maleimide-activated derivative of high-performance DyLight 405 used to fluorescently label sulfhydryl-containing peptides, proteins and other biomolecular probes.DyLight 405has high fluorescence intensity over a broad pH range (pH 4-9) and is more photostable than Alexa Fluor 405, Cascade Blue and AMCA dyes in many 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 405 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.
