DEFINITION

Classification: 424/1.49

Attached to antibody or antibody fragment or immunoglobulin; derivative thereof:

(under subclass 1.11) Subject matter in which the radionuclide or intended radionuclide is attached (bonded, chelated, complexed) to an antibody, or an antibody fragment, or immunoglobulin (e.g. monoclonal antibody); and the derivatives thereof.

(1) Note. Antibodies, per se, including those having

attached thereto a radionuclide, such as monoclonal and polyclonal antibodies, are considered to be compounds and are classified in Class 530, subclasses 387.1+.

(2) Note. Proper for placement here are mixtures or compositions, such as an immune serum or an antiserum, which are disclosed or reasonably believed to have antibodies attached to radionuclide or intended radionuclide.

436, Chemistry: Analytical and Immunological Testing, appropriate subclasses for in vitro test methods including those methods which include injecting a host animal to produce an antibody or antisera if the virus or micro-organism injected is dead. Class 424 provides for such methods, when the virus or micro-organism is live.
