Cy3-PEG2-TCO is a Cy3-based fluorescent reagent containing a two-unit PEG spacer and a trans-cyclooctene (TCO) functional group. It is designed for rapid bioorthogonal conjugation via inverse electron-demand Diels-Alder (iEDDA) reactions with tetrazine-bearing partners and is intended for research use in labeling, imaging, and bioconjugation workflows.

  • Fluorescent Cy3 dye derivative suitable for imaging and labeling.
  • PEG2 spacer improves solubility and reduces steric hindrance during conjugation.
  • TCO functional group enables fast, selective iEDDA click reactions with tetrazines.
  • Supplied as a solid with color ranging brown to reddish brown.
  • High purity (~91.1%) with molecular weight 775.46 g·mol-1.
  • Store protected from light under nitrogen at -20°C; in solvent, store at -80°C for long term.
