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. So this binding process takes place, it tells our plasma cells which types of antibodies to produce. It tells them exactly what type of epitopes are found on that antigen. And then the different types of plasma cells produce let's say antibody one, two and three.
