However, their heterogeneity of size, structure, charge and biological activity has made isolation and purification a challenging problem for immunoche

These lymphocytes may be B cells secreting autoantibodies like those responsible for hemolytic anemia, T cells attacking and destroying target organs such as the thyroid, or mo

Wolfgang Hackbuschy any foreign antigen. It does this by postulating that each lymphocyte can only produce antibodies of a single specificity and that a very large number of distinct lymphocytes exist. That may be restated to say that the universe of foreign antigens is matched by an internal universe of lymphocytes.
