- # 60 Action Of B-lymphocytes
A B-lymphocyte places some of its specific receptor molecules in its cell surface membrane. If it encounters an antigen that binds with this receptor, the B-lymphocyte is activated. It divides repeatedly by mitosis to produce a clone of genetically identical plasma...

| Karl Landsteiner |
? ???Coined: in 1921 by the American biologist of Austrian origin, Karl Landsteiner (1868 ? June 26, 1943). In 1930, Landsteiner received the Nobel Prize for Medicine for his work on differentiating the blood groups
Definition:
A hapten is a small molecule that can stimulate an strong immune response only when it is in combination with a larger molecule such as a protein. Functionally , a hapten is virtually the equivalent of en epitope.
