Thermo Scientific™ DyLight™ 755-4xPEG Maleimide

Thermo Scientific™ DyLight™ 755-4xPEG Maleimide

Thermo Scientific DyLight 755-4xPEG Sulfhydryl-Reactive Dye is a maleimide-activated derivative of our high-performance DyLight 755 Dye used to fluorescently label cysteine-containing peptides, proteins or other biomolecular probes.

The DyLight 755-4xPEG dye contains 4 polyethylene glycol (PEG) chains that are non-cytotoxic, enhance fluorescence and reduce nonspecific binding of conjugates made with them. Conjugates made with DyLight 755-4xPEG Dye can be used as molecular probes for cellular imaging and other fluorescence detection methods. The NIR fluorescence properties of DyLight 755-4xPEG Dye make it especially useful in a variety of biological, chemical, and pharmaceutical applications, including in vivo imaging. The PEG chains also improve solubility of the dyes and labeled molecules in aqueous solution, aid in cell permeability and improve tissue retention.

Features

• High fluorescence intensity—significantly brighter fluorescence than Alexa Fluor™ 750
• PEGylated—improves solubility in aqueous solution and aids in cell permeability
• Specific—maleimide-activated dye labels proteins and other molecules at reduced sulfhydryls (-SH)
