What is the difference between monoclonal and polyclonal antibodies?

Monoclonal antibodies consist of different immunoglobulins recognizing a single epitope on different antigens, whereas polyclonal antibodies consist of different immunoglobulins recognizing many epitopes on an antigen.

Monoclonal antibodies are identical immunoglobulins recognizing a single epitope on different antigens, whereas polyclonal antibodies consist of many different immunoglobulins that recognize many epitopes on an antigen.

Monoclonal antibodies consist of different immunoglobulins recognizing a single epitope on the same antigen, whereas polyclonal antibodies consist of identical immunoglobulins recognizing many epitopes on an antigen.

Monoclonal antibodies are identical immunoglobulins recognizing a single epitope on the same antigen, whereas polyclonal antibodies consist of different immunoglobulins recognizing different epitopes on the same antigen.

Verified step by step guidance

Understand the basic definition of antibodies: Antibodies are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.

Define monoclonal antibodies: Monoclonal antibodies are identical immunoglobulins that recognize and bind to a single specific epitope on the same antigen. They are produced by a single clone of B cells.

Define polyclonal antibodies: Polyclonal antibodies consist of a mixture of different immunoglobulins that recognize and bind to multiple epitopes on the same antigen. They are produced by different clones of B cells.

Compare the specificity: Monoclonal antibodies have high specificity for a single epitope, making them useful for targeted therapies and diagnostic tests. Polyclonal antibodies have broader reactivity, which can be advantageous for detecting a range of epitopes.

Consider the production process: Monoclonal antibodies are typically produced using hybridoma technology, which involves fusing B cells with myeloma cells. Polyclonal antibodies are usually obtained by immunizing an animal with an antigen and collecting the serum.
