Antibody Structure

• Antibodies are produced by...

  B Lymphocytes
• Antibodies are...

  Large Globular Proteins - Y shaped, 4 polypeptide chains, held together by disulfide bridges
• What are the regions on an Antibody molecule?

  Variable and Constant
• The variable region...

  Is the antigen binding site due to amino acid sequence variability
• The constant region...

  Binds and attatches to other cells like Phagocytes
• What is Neutralisation?

  When Antibodies cover the pathogen binding sites to prevent it binding to a host cell and entering the cell
• What is Agglutination?

  When Antibodies bind to many pathogens, so that they can clump them into a large group; preventing them from entering the cell
