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 . .

Iraqi Center for Cancer and Medical Genetics Researches. Application of ELISA. Presence of antigen or the presence of antibody in a sample can be evaluated.. Determination of serum antibody concentrations in a virus test.. Immunological Disorders. Introduction. A. There are three types of immunological disorders. 1. Hypersensitivity. 2. Autoimmune disease. 3. Immunodeficiency. B. Hypersensitivity reactions to usually harmless substances are often called allergies or allergic reactions. Detection By. Precipitation Methods.

(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 .
