Antibodies, as pivotal components of the immune system, have been employed in various scientific and medical fields. The generation of antibodies, as a critical aspect of immunological responses, has garnered significant attention in biomedical research and clinical applications.

Polyclonal Antibody Production procedure

Polyclonal antibodies (pAbs) are a diverse mixture of antibodies produced by different B cell lineages within an immunized host, typically a rabbit or goat. The process begins with the administration of the target antigen, following which the host’s immune system generates a broad spectrum of antibodies recognizing multiple epitopes on the antigen. The antiserum, containing this heterogeneous antibody population, is then collected and may undergo further purification to obtain the desired antibody fraction.

The general procedure to produce polyclonal antibodies is as follows:

1 Antigen preparation

2 Adjuvant selection and preparation

3 Animal selection

4 Injection and ELISA titer testing

5 Blood serum extraction and antibody purification.

Diagnostic Applications of Polyclonal Antibodies (pAbs)

——Broad Reactivity: pAbs can recognize multiple epitopes on an antigen, which is beneficial in diagnostics where a broader recognition spectrum is advantageous.

——Use in ELISA: Like mAbs, pAbs are also utilized in ELISA and other diagnostic assays, especially when detecting a range of antigenic variants is crucial.

Therapeutic Applications of Polyclonal Antibodies

——Antivenom Production: pAbs play a crucial role in antivenom production, where a broad spectrum of antibodies is required to neutralize various toxins present in venom.

——Infectious Diseases: They are also utilized in passive immunotherapy for infectious diseases, providing a broad-spectrum immune response.
