DEFINITION

Classification: 530/388.1

Monoclonal:

(under subclass 387.1) Subject matter involving an antibody or fragment thereof produced by a clone of cells or cell line that is derived from a single antibody-producing cell, wherein said antibody is identical to all other antibodies produced by that clone of cells or cell line.

(1) Note. This subclass provides for antibodies and fragments thereof that are produced by any cloning technology that yields identical molecules, e.g., hybridoma technology, recombinant DNA technology, etc.

(2) Note. Monoclonal antibodies are sometimes termed monoclonal receptors.

(3) Note. This subclass includes monoclonal antibodies whose binding specificities are not disclosed and includes methods of purifying monoclonal antibodies, per se.
