DEFINITION

Classification: 435/345

Immunoglobulin or antibody binds a drug, hapten, hapten-carrier complex, or specifically identified chemical structure (e.g., theophylline, digoxin, etc.):

(under subclass 326) Subject matter involving an animal cell which produces a monoclonal antibody or antigen-binding fragment thereof whose antigen-binding site(s) will combine with a drug, hapten, hapten-carrier complex, or with a specifically-identified chemical structure that is disclosed.

(1) Note. A hapten is a molecule or portion thereof that has little or no antigenicity unless coupled to a carrier molecule that is antigenic. Haptens are usually, but not always, of low molecular weight. Common carriers are proteins such as bovine serum albumin (BSA) and keyhole limpet hemocyanin (KLH).

(2) Note. This is the proper subclass for animal cells producing catalytic antibodies.
