What is antiobody?

Answer 1

An antibody is a protein produced by the immune system in response to foreign substances, such as pathogens like bacteria and viruses. They recognize and bind to specific antigens, which are unique molecules found on the surface of these invaders. This binding can neutralize the pathogen or mark it for destruction by other immune cells. Antibodies play a crucial role in the body’s defense against infections and are also used in various medical applications, including diagnostics and therapies.
