Antigen-Antibody Reaction

An antigen-antibody reaction is a crucial part of the immune response. Antigens are substances, often from pathogens like bacteria or viruses, that can trigger an immune response. Antibodies are proteins produced by the immune system to identify and neutralize these antigens. When antibodies bind to the specific antigens, they mark them for destruction and prevent them from causing harm. This interaction is essential for protecting the body from infections and is also the basis for many diagnostic tests and vaccines, helping the body recognize and respond to harmful invaders effectively.
