Fluorescent Dyes  >  Fluorescent Physiological and Neurological Indicators  >>  Calcein, AM *UltraPure Grade*, 5 mM solution in anhydrous DMSO

Product Name Calcein, AM *UltraPure Grade*, 5 mM solution in anhydrous DMSO
CAS 148504-34-1
Size 200 µL
Catalog # AS-89203
US$ $181
Purity ≥95% by HPLC

Calcein, AM is a cell-permeant and non-fluorescent compound that is widely used for determining cell viability. In live cells the non-fluorescent calcein, AM is hydrolyzed by intracellular esterases into the strongly green fluorescent anion calcein. The fluorescent calcein is well-retained in the cytoplasm in live cells. Hela cells stained with AnaSpec’s Calcein AM fluorescent dye (Cat# AS-89201, AS-89202, AS-89203 and AS-89204).

MCF-7 cells grown in 8-well slide chamber for 2 days. Cells were washed twice before adding 1 uM Calcein AM (AnaSpec cat# AS-89202). Images acquired every 3 seconds and total elapsed time on video is 12 min.
