What is an Antistof?

An antibody is a protein made by the natural immune system. These antibodies (also called antibodies) are developed in response to an infection created by antigens such as bacteria, microorganisms, viruses or other foreign substances. This pathogen is rendered harmless by antibodies binding to antigens. Antibodies are found in the blood or other body fluids. In addition, antibodies may be attached to white blood cells (B lymphocytes).
