PPT-Antigen-antibody reactions

Lets start The immune system is a system of biological structures and processes within an organism that protects against disease To function properly an immune system must detect a wide variety of agents from viruses to parasitic worms and distinguish them from the organisms own healthy tissue .

They are based on two soluble reactants that come together to make one insoluble product, the precipitate (. Agglutination. The interaction between an antibody and a particulate antigen results in visible clumping called agglutination. Particulate antigen include: . Bacteria, . W. hite blood cells, .

Hypersensitivity. 2. Autoimmune disease. 3. Immunodeficiency. B. Hypersensitivity reactions to usually harmless substances are often called allergies or allergic reactions. Dr. . Amany. . Ballow. .

Serology as a science began in 1901. Austrian American immunologist . Karl Landsteiner. (1868-1943) identified groups of red blood cells as A, B, and O. From that discovery came the recognition that cells of all types, including blood cells, cells of the body, and microorganisms carry proteins and other molecules on their surface that are recognized by cells of the .
