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. And then antibody one binds onto epitope one as shown here. Antibody two binds onto the second epitope as shown here. And the third one binds to this third epitope as shown here.
