Calcein-AM

A cell-permeable, non-fluorescent acetoxymethyl ester derivative of Calcein that gets hydrolyzed inside the cell by esterases.


  • Readily bind intracellular calcium resulting in a strong yellowish-green fluorescence
  • Best probe for cell viablilty and cell adhesion
  • Cell-permeable, non-fluorescent acetoxymethyl ester derivative of Calcein


The loss of the acetoxymethyl group also enables calcein to readily bind intracellular calcium resulting in a strong yellowish-green fluorescence. It is the best probe for cell viablilty and cell adhesion due to its greater retention in cells as well and its pH insensitivity in physiological range.
