title: Isolation of (copper, zinc)-thioneins from the livers of copper-injected rats.
abstract: The mixed copper- and zinc-binding proteins, with mol.wt. of approx. 12000, induced in rat liver after injection of copper were isolated and characterized as metallothioneins. Three separate forms were obtained, with 7-11% total metal in the protein, equivalent to 2.6-1.6 cysteine residues/metal atom.
