The document summarizes an experiment examining the effect of hyperthermia on NS0 cells cultured at 39°C for 96 hours compared to a control cultured at 37°C. The mild hyperthermia resulted in slightly lower cell growth but similar viability and apoptosis levels as the control initially. After 72 hours, the hyperthermia-treated cells showed increased apoptosis and decreased viability compared to the control. However, antibody production was significantly higher, up to 30% more total antibody and nearly double the specific antibody production at 96 hours in the hyperthermia-treated cells compared to the control. Further research is needed to understand the mechanisms leading to increased antibody production such as effects on cell cycle and quality of the antibodies produced.
