Abstract
The invention provides targeting radioactive immunoreagents comprising a metal radionuclide ion, a complexing agent having structure A-I, as defined in the specification, and an immunoreactive group covalently bonded to the complexing agent. The present invention also provides novel complexing agents having the structure A-I, as defined in the specification. The targeting radioactive immunoreagents are particularly useful in therapeutic and diagnostic imaging compositions and methods.
