Explanation

A plasma cell is a mature B lymphocyte that is specialised for antibody (immunoglobulin) production. Plasma cells are rarely found in the peripheral blood. They comprise 0.2% to 2.8% of the bone marrow white cell count. These cells produce immunoglobulins of all isotypes, including IgE.
