And what that means is these cloned cells can then go on and find the same exact antigens floating around in our body. Now, what it also does is it induces the process of differentiation. Some of the clone B cells begin to differentiate into plasma cells as well as into memory B cells, the specialized versions of our B lymphocytes. Now, what the plasma cells do is they begin to produce plasma soluble and mobile versions of these B cell receptors that can bind onto antigens. And what these are is our antibodies that we spoke of earlier. So antibodies are soluble and mobile versions of these B cell receptors that are found on the membrane of the B lymphocyte.
