Descrition & Target

Calcein is a highly negatively charged, water-soluble fluorescein derivative. Its fluorescence is nearly independent of pH in the range between 6.5 and 12. The dye can be introduced into cells by microinjection and is useful for cell tracing and for the study of cell membrane integrity and fusion. 9689c5aa-6556-4b3c-b5d1-1e693715ba07 also offers calcein AM, the membrane-permeant version of calcein that hydrolyzes into calcein once inside cells.
