Polyclonal Antibody

To collect antibodies that recognize a specific protein, a protein is injected once into a rabbit, then a second time about three weeks later. The protein will then stimulate the reproduction of cells and produce antibodies that recognize it. These antibodies are polyclonal antibodies. Polyclonal antibodies produced from different clones of B cells, each of them have different binding site for different epitopes on the antigen. Same antigens have different apitopes on them.
