Antibodies recognize specific antigens by identifying certain areas on the surface of the antigen known as antigenic determinants. Once the specific antigenic determinant is recognized, the antibody will bind to the determinant.The antigen is tagged as an intruder and labeled for destruction by other immune cells.Antibodies protect against substances prior to cell infection. Antibodies are produced by a type of white blood cell called a B cell (B lymphocyte).B cells develop from stem cells in bone marrow. When B cells become activated due to the presence of a particular antigen, they develop into cells called plasma cells.ntibodies recognize specific antigens by identifying certain areas on the surface of the antigen known as antigenic determinants. Once the specific antigenic determinant is recognized, the antibody will bind to the determinant.
