But they bind two different locations, two different epitopes on that particular antigen. Now how do we produce polyclonal antibodies? For example, if I'm a biochemist in the laboratory how can I produce these polyclonal antibodies and actually study them? Well, it turns out that it's not that difficult to produce these polyclonal antibodies. So basically we take some type of organism with a functioning immune system, for example a mouse and we inject that mouse with our fluid that contains those antigens. For example, one type of antigen is two, four Dinitrophenol.
