This is possible by a special immune system that produces antibodies and/or activated lymphocytes that attack and destroy specific invading organisms or toxins. Specific defense mechanisms are also referred to as adaptive or acquired immunity (Table 1). Organisms that possess an [...]
In this article we will discuss about the structure of immunoglobulins, explained with the help of a suitable diagram. Identification of antibodies in the serum protein fraction was demonstrated in the classic experiments of A. Tiselius and E.A. Kabat in 1939. However, the basic structure of —globulin molecule was revealed by Rodney R. Porter and Gerald Edehman in 1950s and [...]
