Description

General description

Brij 58 is a nonionic surfactant or detergent for protein extraction and permeabilization of cells. It may be used in the preparation of yeast spheroplasts.

Application

Polyethylene glycol hexadecyl ether, or Brij 58, has been used in a study to assess properties of gemini-conventional surfactant mixtures and their effects on solubilization of polycyclic aromatic hydrocarbons. It has also been used in a study to investigate RNase-sensitive constraint of bacterial nucleoid structure.
