A myeloma MPC-11 cell line, which originated in a mouse plasma cell tumor, was able to proliferate in the absence of serum in a synthetic medium supplemented with transferrin, ethanolamine and selenium. The cells showed almost the same growth rate in this medium as in medium with 10% fetal calf serum added. Immunoglobulins secreted into the serum-free medium by the cells were easily separated from medium components by polyacrylamide gel electrophoresis.
