Thermo Scientific™ DyLight™ 650-4xPEG NHS Ester

Thermo Scientific™ DyLight™ 650-4xPEG NHS Ester

Thermo Scientific DyLight 650-4xPEG Amine-Reactive Dye is a derivative of our high-performance DyLight 650 Dye that can be used to fluorescently label antibodies and other proteins for far-red detection.

The DyLight 650-4xPEG 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 650-4xPEG Dye can be used as molecular probes for cellular imaging and other fluorescence detection methods. The far-red to NIR fluorescence properties of DyLight 650-4xPEG 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™ 647
• PEGylated—improves solubility in aqueous solution and aids in cell permeability
