Description

  • pH-Sensitive fluorescent probe containing one carboxylic acid group.

 

Applications

  • pH-Sensing applications.
  • Fluorescence lifetime applications — this label exhibits a distinct lifetime change upon binding to a biomolecule.

 

Advantages

  • Perfectly suited for excitation with the 594-nm and 635-nm diode laser.
  • Sensitive; high extinction coefficient.
  • pH-sensitive between pH 9 and pH 13, and pH-insensitive between pH 3 and pH 9.
  • Good aqueous solubility. 
  • High photostability; e.g. compared to CypHer 5TM.
