Binding of 241Am to carp cytosolic fractions in vitro.

Recent studies on the competition between Cd and radionuclides have been reported in marine species. The present investigation aims to study the binding of 241Am to freshwater fish cytosolic fraction before and after Cd-treatment. The main organs studied are the liver, kidneys and muscles. The distribution of americium in the liver cytosol of carp cadmium treated shows a preferential fixation on a 10 KDa fraction with high sulfhydril compounds.
