Polyclonal Antibodies

Because one organism contains many different epitopes that the host will recognize as foreign and because the host usually responds by producing antibodies to each antigen, the host's serum will contain various polyclonal antibodies. Polyclonal antibodies used in immunodiagnosis are prepared by immunizing animals (usually rabbits, sheep, or goats) with an infectious agent and then isolating and purifying the resulting antibodies from the animal's serum. However, because individual animals produce different antibodies with different idiotypes (antigen-binding sites), the lack of uniformity in polyclonal antibody reagents requires that different lots be continually retested for specificity and avidity (strength of binding) in any given immunochemical test system.
