Calcein UltraBlue™ sodium salt

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.
