Summary
The comparative effects of Pluronic on cell growth of hybridomas were studied. The addition of 0.05% Pluronic decreased the steady-state cell number in continuous culture by about 12% compared to a non-supplemented culture. In short-term experiments, results demonstrated a gradual decrease in cell number with increasing concentration of Pluronic. Such growth inhibition was found to be a result of lowering the rate of DNA synthesis.
