Gama globulins are synthesized in ?

Ans. is 'c' i.e., Plasma cells Gamma globulins (immunoglobulins) are synthesized by plasma cells. Plasma cells Plasma cells are the antibody secreting cells On contact with its appropriate antigen, the mature B cell undergoes clonal proliferation. The majority of activated B cells are transformed into plasma cells and secrete antibodies. Plasma cells make an antibody of a single specificity, of a single immunoglobulin class and allotype,and of a single light chain type only. An exception is seen in the primary antibody response, when a plasma cell producing Ig M initially, may later be switched to Ig G production. While plasma cell is the best antibody producing cell, lymphocytes, lymphoblasts and transitional cells may also synthesise Ig to some extent.
