Sufficient For 5 uses to label a total of 2mg of IgG using typical conditions
Description DyLight 680-4xPEG NHS Ester
Quantity 5 x 65µg

The DyLight 680-4xPEG 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 680-4xPEG Dye can be used as molecular probes for cellular imaging and other fluorescence detection methods. The far-red to NIR fluorescence properties of DyLight 680-4xPEG 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.


  • High fluorescence intensity – significantly brighter fluorescence than Alexa Fluor™ 680

  • PEGylated – improves solubility in aqueous solution, aids in cell permeability and improves tissue retention in in vivo applications

  • Convenient kit sizes – standard and microscale kit sizes to match your experimental needs

Recommended for:

  • Fluorescence microscopy
  • In vivo or ex vivo imaging
  • Cell-based assays
  • Flow cytometry/fluorescence-activated cell sorting (FACS)
