Viable Cell Stains

Alongside the nuclear stains, Calcein-AM is a suitable probe for fluorescently labeling viable cells. Calcein does not inhibit cellular functions (such as proliferation or chemotaxis). The non-fluorescent Calcein-AM readily passes through the cell membrane of viable cells, and is hydrolyzed in the cytoplasm by intracellular esterases to green-fluorescent Calcein which remains inside of the cell.  In addition, non-radioactive viability assays using Calcein (e.g. PromoKine’s Fluorometric Cell Viability Kit II) are convenient, sensitive and reliable and correlate well with the radioactive 51Cr-release assay.
