Idiotypy of anti-Rh antibodies
Abstract:
Anti-id sera to Rh antibodies were produced by injecting rabbits with purified Rh antibodies. These sera were shown to agglutinate O Rh+ RBC coated by the immunizing antibody and--in some cases--by other anti-D antibodies. Id and cross-reactive id were shown to be located in the antigen-binding and in the non-antigen binding regions of Rh antibodies. An unique example of evolution of idiotypic specificities on human antibodies has been reported. Lastly, we have demonstrated by rosette assay, presence on some PBL of receptors for Fab'2 anti-Rh coating O Rh+ red cells. Rosettes could not be obtained with lymphocytes of a donor and Fab'2 anti-Rh of another individual. Rosettes appeared at a period of time in which the amount of antibody was decreasing.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Blood Transfusion and Agglutination
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
