Thermo Scientific™ DyLight™ 800-4xPEG NHS Ester

Thermo Scientific™ DyLight™ 800-4xPEG NHS Ester

Thermo Scientific DyLight 800-4xPEG Amine-Reactive Dye is a derivative of our high-performance DyLight 800 Dye that can be used to fluorescently label antibodies and other proteins for near-IR detection.

The DyLight 800-4xPEG 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 800-4xPEG Dye can be used as molecular probes for cellular imaging and other fluorescence detection methods. The NIR fluorescence properties of DyLight 800-4xPEG 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—fluorescence comparable to Alexa Fluor™ 800 and IRDye™ 800
• PEGylated—improves solubility in aqueous solution and aids in cell permeability
