Cy5 labeled polyethylene glycol is a near infrared fluorescent PEG derivative that has a maximum absorption at 650 nm and emission around 670 nm. Cy5 labeled PEG derivative can be easily traced from its blue color and strong fluorescence. Additional functionality allows these fluorescent PEG derivatives to be easily conjugated to other molecule or material surfaces.

Physical Properties:

  • Blue or dark blue solid or viscous liquid depends on molecule weight;
  • Soluble in regular aqeous solution as well as most organic solvents;

Storage Conditions:

  • Store at -20 0C, dessiccated Protect from light. Avoid frequent thaw and freeze.
