Abstract (en)

[origin: WO8907271A1] Monoclonal antibodies or immunoreactive monoclonal antibody fragments specific for naturally occurring binding proteins are used to form a monoclonal antibody-binding protein complex by which to detect a ligand in a variety of immuoassay formats. These antibodies or fragments can be labeled or unlabeled and when they are unlabeled then the unlabeled antibody or fragment is reacted with a labeled antibody specific for the unlabeled antibody or fragment. This approach preserves the inherent affinity of the binding protein for the ligand.
