AP555 is an alternative to tetramethylrhodamine (TAMRA, TMR) or Cyanine3 dyes. It is a hydrophilic fluorophore with high fluorescence quantum yield and high photostability. AP555 carboxylic acid is a non-reactive form of AP555 dye, the carboxyl group can interact with hydrazine, hydroxylamine and carbodiimides (such as EDAC) ) amine reaction. AP555 carboxylic acid can be used as a reference standard in experiments involving AP555 dye conjugates.
