| Thermo Scientific DyLight 633 Sulfhydryl-Reactive Dye is a maleimide-activated derivative of high-performance DyLight 633 used to fluorescently label sulfhydryl-containing peptides, proteins, and other biomolecular probes.DyLight 633fluoresces red and has physical properties comparable to other 633 dyes, including Alexa Fluor™ 633, 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.DyLight 633 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.
