Description

  • Hydrophilic, alkyne-reactive reagent for click chemistry containing one azide function. Azides react with C≡C-triple bonds in either a Cu(I)-catalyzed or Cu-free 1,3-dipolar cycloaddition reaction to a triazole.

 

Applications

  • Click Chemistry reagent
  • Fluorescence intensity and fluorescence polarization-based applications
  • Resonance Energy Transfer (RET)

 

Advantages

  • Perfectly suited for excitation with the 635-nm and 650-nm diode lasesr
  • Sensitive; high extinction coefficients and high quantum yields after covalent attachment to biomolecules
  • Quantum yield is highly increased after covalent and non-covalent association with  proteins
  • pH-insensitive between pH 3 and pH 10 
  • Good aqueous solubility: this label does not alter the solubility of the bioconjugate 
  • Photostability: Higher photostability as compared to Alexa FluorTM 647 or Cy5TM
  • Low molecular weight: Seta dyes do not add substantial mass to the conjugates 
  • Ideal for non-radioactive labeling of alkyne-modified proteins, DNA and oligonucleotides
