    An antigen is a foreign protein (such as bacteria or virus). I called it foreign because it is not a normal part of your body. Your cell membranes are designed to recognize that those substances are foreign.

    When such a recognition occurs, a series of chemical reactions occur that result in your body GENerating ANTIbodies. Thus, foreign proteins are called ANTIGENS because they stimulate your body to generate antibodies.

    In many situations, once you are exposed to an antigen, your body will continue to make antibodies for, up to, your life. Thus, you become immune to the antigen.

    So, antibodies fight off antigens.

    Mizz.. Dear

    Every species is unique on this earth though all have similar plasma membrane around the cells. Then what makes all of us different that we can recognize invader inside our body say a bacterial pathogen. Reason is simple the antigens (Generally glycoproteins) on bacterial membranes are different and our Helper T cells (WBC lymphocytes) get activated against them and start synthesizing antibodies to kill these invaders well overall this reaction or your immune response of body is called HUMORAL RESPONSE. Good luck. Do enjoy:
