Antibodies utilized for research and symptomatic intentions are frequently obtained by infusing a lab creature like a rabbit or a goat with a particular antigen.
This so-called polyclonal antibody response is also typical of the response to infection by the human immune system.
Polyclonal antibodies are a mixture of heterogeneous products produced by different B cell clones. They can recognize and bind to many different epitopes of a single antigen. Polyclonal antibodies are produced by injecting an immunogen into an animal. After being injected with a specific antigen to elicit a primary immune response, the animal is given a secondary even tertiary immunization to produce higher titers of antibodies against the particular antigen.
After immunization, polyclonal antibodies can be obtained straight from the serum or purified to get a free solution from other serum proteins. The ability of antibodies to selectively bind a specific epitope present on a chemical, carbohydrate, protein or nucleic acid has been thoroughly exploited through the years, as evidenced by the broad spectrum of research and clinical applications in which they are utilized.
Applications include simple qualitative and quantitative analyses to ascertain the following:. The applications listed in Table 1 are by no means exhaustive. A particular rundown of applications in which polyclonal antibodies PAbs , monoclonal antibodies MAbs , their pieces and forms, either play a fundamental part or have had a massive effect in the essential exploration process.
