Antibodies are antibodies. They are specific proteins known as immunoglobulins, that have a specific structure. They have an antigen binding region, called the Fab fragment, that is extremely variable, and a tail that binds to antibody receptors, called the Fc fragment that only has a handful of variations. The Fc tail defines what kind of antibody the protein is, (i.e. IgG, IgE, IgM, etc.).
Other proteins can bind foreign bodies, the most important of which is the complement system.
To kill things
Vaccines stimulate production of antibodies.
Antibodies
Antibodies are proteins produced by the immune system in response to foreign invaders such as bacteria, viruses, and other pathogens. They help to identify and neutralize these invaders, either by binding to them directly or by marking them for elimination by other immune cells. Antibodies play a crucial role in protecting the body against infections and diseases.
Antibodies are bound to the surface of a B cell. These antibodies serve as receptors that allow the B cell to recognize and bind to specific antigens. This binding process helps initiate the immune response by activating the B cell to differentiate into plasma cells that secrete antibodies.
Enzymes and antibodies are examples of proteins. They are molecules made up of amino acids that perform specific functions in the body, such as catalyzing chemical reactions (enzymes) and recognizing and binding to specific molecules (antibodies). DNA and RNA are nucleic acids that carry genetic information and serve as templates for protein synthesis.
Monoclonal antibodies (mAb or moAb) are monospecific antibodies that are made by identical immune cells that are all clones of a unique parent cell, in contrast to polyclonal antibodies which are made from several different immune cells. Monoclonal antibodies have monovalent affinity, in that they bind to the same epitope. Given almost any substance, it is possible to produce monoclonal antibodies that specifically bind to that substance; they can then serve to detect or purify that substance. This has become an important tool in biochemistry, molecular biology and medicine. When used as medications, the non-proprietary drug name ends in -mab (see "Nomenclature of monoclonal antibodies"), and many immunotherapy specialists use the word mab anacronymically.
No they do not. B cells synthesize the antibodies.
Antibodies are made in the lymph nodes.
Function of antibodies is to neutralizes the antigens that enters.
