CyDye fluors are versatile fluorophores designed for a broad range of applications. CyDye fluors produce high sensitivity and highly reproducible performance at a biologically suitable pH range of 3 to 10. The use of multicolor CyDye flours enables multiplexing without crosstalk for high accuracy.

Cy3 NHS Ester provides targeted and specific labeling of amine residues on antibodies, peptides, or oligonucleotides.

  • Readily dissolves in and produces a stable signal in aqueous buffers (no need for organic solvents)
  • High purity and thorough QC testing generate high levels of chromophore and reactive dye content
  • Narrow excitation and emission bands result in discrete signals from each fluor
  • Demonstrates larger polarization range than conventional fluors
  • Fluorescence lifetime of 2.8 ns
  • High fluorescence intensity
  • Low non-specific binding


5 mg
Foil packs of pre-measured dried dye
Soluble in aqueous solutions
For labeling via Amine groups, CyDyes are suitable for use in applications such as Fluorescence resonance energy transfer (FRET), time resolved-Fluorescence resonance energy transfer (TR-FRET) and Fluorescence polarization (FP)
