Description

Application

Calcein has been used:

in whole cell staining
in histomorphometry and micro-computed tomography
to label active bone-forming surfaces

Biochem/physiol Actions

Calcein is a calcium-dependent fluorescent molecule. It is mainly required to study bone metabolism under in vivo conditions and helps in the staining of pit area under in vitro conditions. Calcein is used for the fluorometric determination of calcium and EDTA (ethylenediaminetetraacetic acid) titration of calcium.
