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
