Antibodies are proteins secreted by the immune system's B cells to recognize, bind, and neutralize antigens that are unique to organisms such as viruses and bacteria. Antibodies, because of their role in the detection and identification of antigens, can serve as a lifeline for scientific, clinical research, and diagnosis.
These antigens are usually proteins, but can also be nucleotides, small molecules, or macromolecules. The ability of an antibody to bind to an antigen effectively depends on the sequence of antigen-binding surfaces, known as the epitope, and how well the epitope matches the antibody-binding surface sequence.
Antibodies are structured as Y-shaped molecules, with the tail end being responsible for effector function and allowing the antibody to interact with other cells of the immune system. On the internet, you can learn more about the bunny monoclonal antibody service.

The ability to promote the continuous production of antibodies in host cells, which are then collected and purified for research and clinical use, is key to producing monoclonal/polyclonal antibodies.
What's the dissimilarity between polyclonal and monoclonal antibodies?
When animals are given immunogens (antigens), the primary immune response produces antibodies that identify and bind to several antigen epitopes. Polyclonal antibodies are secreted antibodies that are produced by a large number of plasma cells.
Monoclonal antibodies are thought to be made by the same B cells, which are clones of a single stem cell. This means that monoclonal antibodies can only recognize and bind to the same antigen epitope, reducing the risk of cross-reactivity.
