Production and Purification of Polyclonal Antibodies

Polyclonal antibodies are derived from multiple B-cell clones that have differentiated into antibody-producing plasma cells in response to an immunogen. Polyclonal antibodies raised against a single molecular species of antigen recognize multiple epitopes on a target molecule resulting in signal amplification in indirect immunoassays, including immuno-electron microscopy. In this chapter, we present a basic procedure to generate polyclonal antibodies in rabbits.
