Description

  • Hydrophobic fluorescent dye. Fluorescent probe.

 

Applications

  • Cell staining
  • Fluorescent probe for proteins
  • Dye for beads

 

Advantages

  • Perfectly suited for excitation with the 380, 404, 635 and 670-nm diode lasers and UV light
  • Sensitive; high extinction coefficients and quantum yields in presence of proteins
  • Quantum yields increase upon non-covalent association with biomolecules
  • pH-insensitive between pH 3 and pH 10 
  • High photostability; e.g. compared to fluorescein or Cy5TM
