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. So we can inject two, four Dinitrophenol into the mouse, into the blood of the mouse by using a syringe. So we inject once we wait three weeks, we inject the second time, we wait three weeks. And after a total of six weeks we take another syringe and we draw blood from that mouse.
