![]() ![]() The monoclonal / polyclonal antibody production technique depends on the ability to stimulate the B cells of a host species to continuously produce antibodies, which are subsequently harvested and purified for research and clinical use. Read about our brief history of antibodies here. Each arm of the Y has a variable region which is specific to recognising the epitope on an antigen. The ability of an antibody to efficiently bind an antigen depends on the binding sequence on the surface of the antigen, known as the epitope and how well the epitope matches the sequence on the binding surface of antibody.Īntibodies are structured as Y-shaped molecules where the tail end is responsible for the effector function and allows the interaction of the antibody with other cells of the immune system. These antigens are usually proteins but can be nucleotides, small molecules or macromolecules. Antibodies are arguably the lifeline of scientific, clinical research and diagnostics due to their role in detecting and identifying antigens 4. What is an antibodyĪntibodies are proteins secreted by B cells of the immune system to detect, bind and neutralise antigens unique to organisms such as viruses and bacteria. With the availability of multiple options, how do you decided whether a monoclonal or polyclonal antibody is right for your experiment? Why is it best to choose rabbit monoclonal antibodies over other regular monoclonal or polyclonal antibodies such as rat or mouse? To address this, let's first look at antibodies and why they are so vital to scientific and medical research. However, the initial technique has since been modified with variations that meet multiple specific needs 3. Khler and César Milstein first described the hybridoma technique for the production of monoclonal antibodies in 1974 1,2, antibodies have become indispensable to molecular biology and can be produced in several host species. When it comes to identifying proteins in research or developing therapeutics for clinical use, antibodies have become uniquely placed as the most suitable option.Įver since Georges J.F. When the antibody titer has reached an acceptable level, the production of polyclonal antibodies should be ended.The benefits of choosing rabbit monoclonal antibodies over regular monoclonal or polyclonal antibodies Introduction Prior to the priming immunization, following the primary and each booster immunization, the animal is bled and serum prepared from whole blood. Booster immunizations are started 4 to 8 weeks after the priming immunization and continued at 2- to 3-week intervals. In the presence of adjuvant, the protein antigen is injected intramuscularly, intradermally, or subcutaneously into an animal of the chosen species. ![]() Freund's Adjuvant is one of the most commonly used adjuvants in research. Rabbits provide as much as 25 ml of serum from each bleed without significant harmful effects.Īdjuvants are used to enhance the immune response for pAb production. Rabbits are the usual animal of choice because they are genetically divergent from the human and mouse sources of the proteins most often studied. The choice of animals for the production of polyclonal antibodies depends upon the amount of antiserum desired, the evolutionary distance between the species from which the protein of interest has been derived and the species of the animal to be immunized, and prior experience with the immunogens.
