Introduction To order Documents Related Products Introduction The amine-reactive difluorocarboxyfluorescein, succinimidyl ester, 5-isomer can be used to create green fluorescent bioconjugates with excitation/emission maxima ~496/524 nm. This fluorinated analog of fluorescein overcomes some of the key limitations of fluorescein, including greater photostability and a lower pKa (pKa ~ 4.7 versus 6.4 for fluorescein), making its fluorescence essentially pH insensitive […]
