β¦ Synopsis
Relatively high levels of nutrients and low levels of waste products were maintained in cultures of hybridoma cells by dialysis against growth medium supplemented with fetal calf serum (FCS). This resulted in a greater than ten fold increase in cell density and monoclonal antibody titre compared to conventional batch cultures. Exclusion of FCS from the dialysing growth medium resulted in cell death, indicating that a low molecular weight serum component was necessary for growth. This study indicates that nutrient depletion limits hybridoma cell growth in conventional batch culture and also provides a simple and economical means of producing relatively high titre monoclonal antibody an vitro.

## Abstract **BACKGROUND:** Many reports have suggested that mild hypothermic culture conditions improve the specific monoclonal antibody (mAb) productivity of mammalian cells. The effect of active hypothermic growth on the mAb productivity of the hybridoma C~2~E~7~ was investigated. Hybridoma grow
