Antibodies are proteins produced by B white blood cells and used by the immune system to struggle against disease. B cells generate the antibodies that cover invading microbes and allow killer cells (macrophages), to overwhelm and devastate the foreign cells. Because invading cells have some isotopic antigens, one line of monoclonal antibodies is not as proficient. The body creates polyclonal antibodies that identify unusual variations of the same antigen on an invading microbe and it is very important in immunity.

Polyclonal antibody is a type of antibody that is obtains from B cells. B cells are lymphocyte that plays a crucial role in the body's immune system. The general use of polyclonal antibodies is as an antitoxin to take care of poisonous bites and stings. They can also donate passive immunity to various types of ailments in human body, such as Ebola infection. The researchers normally create polyclonal antibodies by immunizing a mammal and storing the resulting serum. This process must be performed in a highly developed biomedical research laboratory.

These types of antibodies are developed from various ...
... clonal populations with specificity to different epitopes on one antibody particle. Polyclonal antibodies are useful against a broad range of pathogens. However, they are not easy to create. The quantity and capacity of polyclonal antiserum acquired differs with each animal and even in the same animal over a span of time. Hence, the availability polyclonal antibodies are inadequate and its nature is subject to change even during the route of production. In the other hand Monoclonal antibodies are created from only one clone and have one specific epitope. To generate monoclonal antibodies, you need to immunize an animal, such as, rabbit and then gather the immune cells from the spleen of that animal. They can also be generated by using in-vitro cell culture systems. Under favorable conditions, unlimited creation of monoclonal antibodies is possible.

Besides these, rabbits are the most commonly used laboratory animal species for polyclonal antibody production due to optimum size, ease of handling, the availability of specific pathogen free rabbits and capability of creating moderate quantities of high-quality and affinity antibody from a variety of antigenic substances. Some other species are also used for polyclonal antibody production such as mouse, chicken, goat, sheep and rat.

When it comes to the humeral response or antibody secretion that is generated by B lymphocytes have specific immunoglobulin receptors on their surface. But an immunogen encourages the immune system of the body; plasma cells that have separated from B lymphocytes produce antibodies in the blood stream.

All the antibody molecule have the capability to identify a specific site, called epitope, (monosaccharide units or chain of 5-6 amino acids) on the antigen and bind to it. Antibodies have been also used by medical researchers in diagnosis, treatment and prevention of various types of physical disorders.
