What are Polyclonal Antibodies?
Download the white paper.
Polyclonal antibodies are a mixture of antibodies from multiple B-cell clones of a host animal that can recognize multiple epitopes on an antigen. Their unique binding characteristic to different epitopes can help amplify their signal, leading to increased sensitivity and better detection. Unlike monoclonal antibodies, created by selecting a single B-cell clone, polyclonal antibodies occur naturally through the immune response. Numerous applications, including Western Blot, ELISA, immunohistochemistry, and immunoprecipitation, can be carried out using polyclonal antibodies. Polyclonal antibody therapeutics are also commonly utilized in medicine for virus and toxin neutralization and immunoglobulin replacement therapy (3). In diagnostics, polyclonal antibodies are used for pathology and lateral flow tests, among others.
There are known limitations, such as limited supply and off-target binding of these antibodies. New technologies readily overcome these issues, such as stringent validation procedures to maximize lot-to-lot reproducibility. With innovative methods available to overcome the limitations of polyclonal antibodies, they remain excellent cost-effective tools for researchers, diagnostic developers & drug developers alike.
Benefits of Polyclonal Antibodies
- Clonal Properties:
- Due to their ability to detect several target protein epitopes, polyclonal antibodies have a high sensitivity to the target protein.
- Biophysical Diversity:
- Polyclonal antibodies are more stable than other antibodies when environmental factors cause other antibodies’ inactivation, lability, or precipitation.
- Provides researchers with modification opportunities, including:
- Host species
- Antigen quantity
- Amount and distribution of injection sites
- Antigen injection frequency
- Adjuvant type
- Adjuvant quantity
- Quicker Production timeline
- Development and production are done in parallel
- Competitive pricing
