Description

Widely used fluorescent calcium indicator.

Calcein, also known as fluorexon, is a fluorescent dye with excitation and emission wavelengths of 495/515 nm, respectively. Calcein self-quenches at concentrations above 70mM and is commonly used as an indicator of lipid vesicle leakage. It is also been used as a complexometric indicator for titration of calcium ions with EDTA, and for fluorometric determination of calcium. Calcein can also be used for study of endocytosis
