Abstract Mouse peritoneal exudate cells induced by casein enhanced in vitro antibody production rate per cell of a hybridoma in co-culture. Culture supernatant of the exudate cells also enhanced three-fold the antibody productivity when added to cultures of a hybridoma at 10% (v/v). Hence the enhancement of antibody productivity by the exudate cells seemed to be caused by soluble enhancing factors secreted by the exudate cells. The exudate cells maximally secreted the enhancing factors when harvested from mice on day 4 of the induction period following the injection of casein. A semi-continuous culture of the hybridoma demonstrated the applicability of the culture supernatant to enhance antibody production by producing a two-fold increase over the control for seven days when supplemented with the supernatant at 5%. Significant amounts of interleukin-6 were detected in culture supernatant of the exudate cells. Interleukin-6 obtained from other sources enhanced the antibody productivity two-fold when added to the hybridoma culture at the concentration of 5 unit/ml. Interleukin-6, therefore, is expected to be one of the principal antibody enhancing factors secreted by the exudate cells. Other interleukins examined, that is, interleukin-1 to-5 did not enhance the antibody productivity.
