What are minimal and maximal concentrations of Poloxamer recommended? Any correlations with cell mass?


This is mainly cell line dependent – we saw effective protection between 0,5-2 g/L in our stress test, which is of course a simplified model. According to literature, concentrations up to 5 g/l have been used for very stressful conditions (high VCD Perfusion), providing protection without any negative side effects. As a minimum we have also seen very few customers using <0,5g/L Poloxamer 188 in their processes.
