Bifunctional chelating agents and process for their production

摘要

There are provided bifunctional chelating agents, which are analogues of EDTA, conjugates of same with a variety of haptens and conjugates of such conjugates with haptens with certain metals, forming metal complexes. The metal complexes have a variety of uses, among these various assays for the determination of haptens and macromolecules. There is also provided a process for the production of the above. There are provided radioimmunoassays based on the above conjugates with metal cations.
