Although FITC reagents have been predominantly used to prepare green fluorescent bioconjugates, the low photostability and pH-dependent fluorescence of FITC bioconjugates make researchers search for alternative fluorophores in bioconjugations. Among green fluorophores, CR110 reagents give more photostable and pH-independent bioconjugates that have the absorption maximum around the preferred 488 nm excitation wavelength.
