Now this is our collection of three identical monoclonal antibodies which were built by the same type of plasma cell. And so what that means is they will all bind to the same exact epitope on that antigen. So let's suppose the orange epitope. 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.
