| Abstract: | A metallothionein-like protein (MLP) was isolated from naturally cadmium-contaminated lobster hepatopancreas, gills, and green glands. Between 76–99% of the total cadmium was associated with this protein (molecular weight 9,500 daltons) while the remainder was associated with both high (68,000 daltons) and low (<6,000 daltons) molecular weight proteins. MLP was not present in uncontaminated lobster hepatopancreas and only 1% of the total cadmium was associated with the gel filtration fraction corresponding to the protein. |
