So we produce a different collection of these different types of antibodies. And even though these different antibodies are for a specific antigen, they can bind to different epitopes on that antigen. So this is the difference between monoclonal and polyclonal antibodies. So let's take a look at the following diagram that describes the binding process between monoclonal antibodies and antigens. So we have 123456 of these specific identical antigens and we have one, two, three different epitopes on each one of these antigens. We have the orange one, we have the brown one and we have the pink one.
