So that means once they form that antibody antigen complex, all of these antigen binding sites on the three monoclonal antibodies will bind to these orange epitopes as shown in the following diagram. Now to summarize the difference between monoclonal and polyclonal antibodies, let's take a look at the following diagram. So we have monoclonal antibodies and polyclonal. Now mono simply means we have a collection of identical plasma cells, so a single type of plasma cell and they produce identical antibodies which bind to an identical epitope found on that specific antigen. But when it comes to Polycal antibodies, polymers, we have a collection of different types of plasma cells and so they produce these different types of antibodies for that specific antigen and they combine to all different types of epitopes found on that specific antigen. So this is the main difference between monoclonal and polyphonal antibodies.
