Notes: Oregon Green™ 488 is a fluorinated fluorescein dye.{58804,58805} It exists as a tautomer in aqueous solutions.{58805} Oregon Green™ 488 has minimal pH dependence at physiological pH but it can be used as an indicator for intracellular pH due to its low pKa of 4.8.{58805,58806} It is less susceptible to photobleaching than fluorescein. Oregon Green™ 488 has been conjugated to antibodies and proteins, as well as DNA, for use in labeling and detection.{58805,58807,58806} It displays excitation/emission maxima of 490/514 nm, respectively.{58804}
