![]() ![]() In some cases, these antibodies can disable pathogens such as viruses directly due to the binding action. These antibodies then bind specifically with the foreign molecule and allow the immune system to eliminate the molecule from the system. Once antibodies with sufficient specificity to the epitope can be encoded, the B cell begins to release antibodies into the bloodstream. Once Antigen Presentation to the B cell lymphocytes has occurred, a process known as Somatic Hypermutation allows the B cell to begin coding for a new antibody that will contain a unique Antigen Binding Site in the variable region that is capable of binding specifically to an epitope from the antigen.Įach B cell lymphocyte produces one unique antibody against one unique epitope. When an organism’s immune system encounters a foreign molecule (typically a protein) for the first time, specialized cells such as macrophages and dendritic cells capture the molecule and begin breaking it down so that it can present these antigens to B cell lymphocytes. Although detailed mechanics of the immune response are beyond the scope of this site, it is useful, in the context of developing a custom antibody, to have an overview of how antibodies are produced by the immune system. ![]()
