Thermo Scientific™ DyLight™ 633 Maleimide

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 633 fluoresces 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.

Features

• High performance—DyLight 633 shows brighter fluorescence than Alexa Fluor 633
• Specific—maleimide-activated dye labels proteins and other molecules at reduced sulfhydryls (-SH)
• Efficient labeling methods—well-characterized chemistry and optimized protocols provide for reliable, high-quality labeling
• Optimized antibody labeling procedure—complete protocol for IgG reduction and labeling and calculating the labeling efficiency
