The long‐term distribution of antibody‐forming cells

Abstract

Abstract Previous experiments suggested that the spleen might not be the chief source of serum antibody synthesized several months after the immunization of mice by sheep erythrocytes; this has been confirmed for classes other than γM. The anatomical location of the cells making the antibody is not the same for each class. The thymus contains a relatively greater number of non‐γM antibody‐producing cells late in the response than it does in the first three weeks after immunization.
