Abstract

Antibody producing human B-lymphocytes are produced by a process which comprises culturing human B-lymphocytes in a tissue culture medium in the presence of an antigen; helper signal producing agents comprising monocytes or monocyte conditioned medium containing Interleukin 1 (I1-1), and helper T-lymphocytes or helper T-lymphocyte replacing factor; and human serum; and thereafter recovering the antibody producing cells from the medium.
