Lubrol 17A17
Lubrol 17A17 is a polyoxyethylene linear alkyl ether produced by ethoxylation of cetyl-stearyl alcohols.
It is a solid non-ionic surfactant and O/W emulsifier supplied in flakes. In cell biology, it is above all used for investigation on lipid rafts, the cholesterol- and glycosphingolipid-rich membrane areas, which play an important role in many cellular processes, e.g. signal transduction. Furthermore it is used for cell and tissue lysis, for the isolation and characterization of membrane-bound enzymes, transporter proteins, and in some applications for column chromatography of membrane components.
