[Method of measurement of cadmium influx by fura-2 titration in MDCK cell evidenced. Fluorescence video-microscopy study].

Cadmium influx rate in mammal kidney cells (MDCK) is analyzed using an original method based on fura-2 titration. The method relies on the high affinity of the fluorophore for the metal. It follows that the excitation spectrum shift of fura-2 can be linearly correlated to the influx rate of cadmium.
