General description

Kolliphor® P 188 is a non-ionic amphiphilic copolymer, which has a central chain of hydrophobic polyoxypropylene and a hydrophilic polyoxyethylene at the ends.

Application

Kolliphor® P 188 has been used as a component of cell-dissociation/minimal essential media (MEM) to sort tumor cells using EpCAM antibody-conjugated magnetic beads.
Kolliphor® P 188 has been used as a supplement in F17 medium for the culture of HEK293-6E cells. It has also been used as a component of flow cytometry (FACS) buffer as a non-ionic detergent that protects cells from hydrodynamic damage.

Biochem/physiol Actions

Kolliphor® P 188 exhibits cytoprotective, hemorheological, anti-inflammatory, antithrombotic activities. It maintains the stability of membrane barrier function. P188 lowers surface tension and hydrophobic-based cellular adherence. It also inhibits lipid peroxidation stimulated by Fe2+ and H2O2.
