Immunoglobulin antibody molecule. Computer model showing the molecular structure of an immunoglobulin (Ig) molecule. Each Y-shaped molecule has two arms (top) that can bind to specific antigens,for instance bacterial or viral proteins. In doing this they mark the antigen for destruction by phagocytes,white blood cells that ingest and destroy foreign bodies. Antibodies can also kill some pathogens directly,and can neutralise toxins | |
