The concentration-specific response of metallothioneins in copper-loading freshwater bivalve Anodonta cygnea.

Metallothioneins (MTs) from digestive gland of freshwater bivalve mollusc Anodonta cygnea, exposed to 10 or to 200 microg x l(-1) copper ions during 14 days, were resolved using subsequent gel-permeation and ion-exchange chromatography on MT-1 and MT-2. In both groups of treated molluscs the content of copper in MT-2 was elevated twice. The significant… CONTINUE READING
