Calcein UltraBlue AM

Calcein UltraBlue AM 10×50 µg is a cell-permeant fluorescent dye commonly used for live cell viability, cytotoxicity, and cell tracking assays. Once inside viable cells, it is hydrolyzed to emit a bright blue fluorescence, enabling sensitive detection in flow cytometry, fluorescence microscopy, and plate-based assays. Supplied in a convenient 10×50 µg format, it offers reliable performance for consistent and reproducible results in life science research.
