Creatine phosphokinase (CPK) loses enzyme activity after direct iodination by the chloramine-T, thallic trichloride and lactoperoxidase methods. Radioiodination of CPK without loss of enzyme activity can be achieved by Bolton-Hunter reagent which conjugates at the N-terminal or e{open}-lysyl NH2 group of the protein.
