Antibodies (also known as immunoglobulins, abbreviated (Ig) are gamma globulin proteins that are found in blood or other bodily fluids of vertebrates, and are used by the immune system to identify and neutralize foreign objects, such as bacteria and viruses. As an antigen is injected into the mammal, it induces the B-lymphocytes to produce IgG immunoglobulins specific for the antigen. The unique part of the antigen recognized by an antibody is called the epitope. These epitopes bind with their antibody in a highly specific interaction. Polyclonal antibodies (or antisera) are antibodies that are obtained from different B cell resources. They are a combination of immunoglobulin molecules secreted against a specific antigen, each identifying a different epitope. Due to polyclonal antibodies recognize multiple epitopes on any one antigen, cause agglutination and precipitation reactions, it is widely used in the field of immunological diagnosis.

Polyclonals can help amplify signal from target protein with low expression level, as the target protein will bind more than one antibody molecule on the multiple eptitopes. Due to recognition of multiple epitopes, polyclonals can give better results in IP / ChIP .Polyclonal antibodies are often the preferred choice for detection of denatured proteins.
