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. So polyclonal simply means we have poly so many different types of plasma cells and so we produce many different types of antibodies but all these antibodies will still bind to that same type of antigen. The only difference is they will bind to different locations on that antigen. That's what we mean by polyclonal antibodies.
