Description générale

Polyoxyethylenesorbitan monopalmitate, or TWEEN 40, is a non-ionic detergent.

Application

Non-ionic detergent used for cell lysis, nuclei isolation and cell fractionation.
Polyoxyethylenesorbitan monopalmitate, or TWEEN 40, has been used in a study to assess the determination of iodide in urine based on a chemiluminescence system. It has also been used in a study to investigate the delivery of astaxanthin and canthaxanthin to HepG2 cells.
