Thermo Scientific™ DyLight™ 800 Maleimide

Thermo Scientific DyLight 800 Sulfhydryl-Reactive Dye is a maleimide-activated derivative of high-performance DyLight 800 used to fluorescently label sulfhydryl-containing peptides, proteins and other biomolecular probes.

DyLight 800 is a near-IR fluor that is invisible to the naked eye but increases the staining options when using infrared imaging systems. DyLight 800 has spectral properties that are very similar to other near-IR dyes, including Alexa Fluor™ 790 and IRDye™ 800. 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 800 replaces Alexa Fluor 800 and IRDye 800 for near-infrared staining
• 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
