product M1255, Calcein Blue to is used to stain cells, but it will stain living or dead cells. For a cell viability stain, one can use Calcein Blue AM. The difference between Calcein Blue and Calcein Blue AM is the methyl-iminodiaceitc acid group that chelates the divalent metal has acetoxymethyl esters on it in Calcein Blue AM. The esters are cleaved inside of viable cells, but remain on the molecule in the absence of active esterases. So, if you use M1255 it will stain all the cell whether alive or dead.

Description générale
Calcein Blue is a cell-permeable dye that stains viable cells. Upon entering the cell, intracellular esterases cleave the acetoxymethyl (AM) ester group, yielding the membrane-impermeable Calcein Blue fluorescent dye. The staining applications of Calcein blue include tumor tissues, mineralized tissues, bone, amino acids, and many more.
Application
Calcein blue has been used fluorescent labeling of the mineralised sections of bone. Calcein blue AM ester hydrolyzed to calcein blue is suitable as a a viability stain, both microscopically, and in fluorescence activated cell sorting systems. It is also used as a merker of living cells like Schwann cells at neuromuscular junctions.
