Abstract
The radioactive iodine compound of this invention or an intermediate for preparing the compound is represented by the following formula (I): ##STR1## wherein R is H or .sup.125 I. The radioactive compound can readily introduce a radioactive isotope element such as .sup.125 I into an antibody molecule without damaging the activity of the antibody molecule. Therefore, the compound can preferably be used to label an antibody of immunoradiometric assay, and allow a higher degree of measurement sensitivity.
