Thermo Scientific™ DyLight™ 405 Maleimide

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 405 has 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.

Features

• High performance—DyLight 405 shows brighter fluorescence than Alexa Fluor 405, Cascade Blue and AMCA
• 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
