Abstract: | The hydrogen peroxide-generating property of glucose oxidase was used in combination with the catalytic property of lactoperoxidase to radioiodinate polypeptide hormones with 125-iodine. This rapid, gentle, enzymatic method reproducibly results in higher yields of iodinated hormones for use in radioimmunoassays. |
