General description

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.

In the immune system, degranulation/exocytosis from lymphocytes is crucial for life through facilitating eradication of infected and malignant cells. Dysfunction of the NK cell exocytosis process has been implicated with devastating immune diseases, such as familial hemophagocytic lymphohistiocytosis, yet the

Skeletal muscle is a highly regenerative tissue, but muscle repair potential is increasingly compromised with advancing age. In this study, we demonstrate that increased NF-κB activity in aged muscle fibers contributes to diminished myogenic potential of their associated satellite cells.
