Description

  • pH-sensitive fluorescent probe containing two carboxylic groups.

 

Applications

  • pH-sensing applications.

 

Advantages

  • Perfectly suited for excitation with the 404, 370, 635, 650, and 670-nm diode lasers and LEDs.
  • Sensitive; high extinction coefficients and high quantum yields up to 20% after covalent attachment to proteins. 
  • pH-sensitive between pH 7 and pH 11, and pH-insensitive between pH 3 and pH 7.
  • Good aqueous solubility.
