Product Name Calcein; AM *UltraPure Grade* *Small Package*
CAS 148504-34-1
Size 50 µg x 20
Catalog # AS-89204
US$ $259
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# 89201, 89202, 89203 and 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# 89202). Images acquired every 3 seconds and total elapsed time on video is 12 min.
