Calcein UltraBlue™ AM

Calcein UltraBlue™ AM is a cell-permeable version of Calcein UltraBlue™. Upon getting into live cells the weakly fluorescent Calcein UltraBlue™ AM is hydrolyzed into Calcein UltraBlue™ that has the excitation/emission maxima similar to those of Calcein Blue, DAPI, Hoechst and AMCA. This exceptional spectral separation from the typical green and red fluorophores (such as FITC, TMR and Texas Red) provides additional options for multiplexing experiments. Calcein UltraBlue™ has similar spectral properties to those of Calcein Blue. However, compared with Calcein Blue, Calcein UltraBlue™ has higher photostability and stronger fluorescence intensity at physiological pH, making it a more robust fluorescent probe than Calcein Blue.
