1. Adjective:

   • Forming or derived from a single clone: Describes something, especially a population of cells or antibodies, that originates from and is genetically identical to a single ancestor cell.

2. Noun:

   • Any of a class of antibodies produced in the laboratory by a single clone of cells: A type of antibody made by identical immune cells that are clones of a unique parent cell. These antibodies are identical and target one specific antigen.

Examples of Usage
