Product Description
Poloxamers is a difunctional block copolymer surfactant terminating in primary hydroxyl groups. A nonionic surfactant that is 100% active and relatively nontoxic. Poloxamers 188 has a molecular weight of 8000 and consists mainly of polyoxyethylene (approx. 80%). It is applied in the culturing of mammalian cells in large batches. It prevents the sticking of air bubbles to cells, which develop during mixing within the fermentor, stabilizes the foam on the surface or improves the resistance of the cell membrane against hydrodynamic shearing.

LS 105-02 contains 100.0 g/L Poloxamers 188 in cell/tissue culture grade water (LS 016-01).
