Question

Antibodies produced by a group of identical B-cells against a single epitope of an antigen is called

• A. Polyclonal antibodies
• B. Monoclonal antibodies
• C. Antihapten antibodies
• D. Somaclonal antibodies

Answer 1

The correct option is B Monoclonal antibodies

• Monoclonal antibodies are antibodies that are made by identical immune cells that are all clones of a unique parent cell.
• Monoclonal antibodies can have monovalent affinity, in that they bind to the same epitope (the part of an antigen that is recognized by the antibody).
• In contrast, polyclonal antibodies bind to multiple epitopes and are usually made by several different plasma cells lineages. Hence, Antibodies produced by a group of identical B-cells against a single epitope of an antigen is called Monoclonal antibodies.

So, the correct answer is 'Monoclonal antibodies'.
