Beschreibung

Allgemeine Beschreibung

Tween^®20 is a polyoxyethylene sorbitol ester that belongs to the polysorbate family. It is a nonionic detergent having a molecular weight of 1,225 daltons, assuming 20 ethylene oxide units, 1 sorbitol, and 1 lauric acid as the primary fatty acid. The ethylene oxide subunits are responsible for the hydrophilic nature of the surfactant, while the hydrocarbon chains provide the hydrophobic environment. Sorbitol forms the backbone ring to which the ethylene oxide polymers are attached.[1]

Anwendung

Anionisches Reinigungsmittel

Tween 20 has been used along with PBS to wash plates in ELISA technique.[2]
