Thermo Fisher, O6149, Oregon Green™ 488 Carboxylic Acid, Succinimidyl Ester, 6-isomer

Oregon Green™ 488 Carboxylic Acid, Succinimidyl Ester, 6-isomer The amine-reactiveOregon Green™ 488 carboxylic acid, succinimidyl estercan be used to 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 in the physiological pH range.
