Now the thing about antigens is many antigens contain many epitopes. So many regions where antibodies can actually be bound to. In this particular case we only show one epitope. But in this case we show one, two, three different types of epitopes and the plasma cells of our body realize that and our immune cell, what it does to basically create a more effective response is once the antibody antigen complex is formed that signals different types of plasma cells to proliferate and form more plasma cells. And these different types of plasma cells begin to produce different types of antibodies that might have a slightly different type of mass and slightly different type of property. But all these antibodies produced will bind to that same type of antigen and these are known as polyclonal antibodies.
