DEFINITION

Classification: 424/1.53

Attachment via an added element (e.g., bifunctional compound or coordinate, coupling agent, spacer compound, bridging compound, conjugated chelate):

(under subclass 1.49) Subject matter in which the radionuclide or intended radionuclide is attached (bonded, chelated, complexed) to an antibody, antibody fragment, immunoglobulin, or derivative thereof via an added, interposed linking means, comprising at least one atom, between the radionuclide and the antibody, antibody fragment, immunoglobulin, or derivative thereof.

(1) Note. Examples of terms used to describe the subject matter proper for placement in this subclass include: bifunctional compound or coordinate, spacer compound, bridging compound, conjugated chelate, chelating group, coordination complex, coupling agent, and conjugation agent.

(2) Note. In the absence of a disclosure of an added attachment means the reference is not properly placed in this subclass, and is proper for subclass 1.49, above.
