Brij 35, an alkyl polyethoxylate, is a mild surfactant suitable for the isolation of functional membrane complexes.

This non-ionic surfactant has been successfully employed in the crystallization of the integral membrane protein cytochrome c oxidase.

Brij 35 can also be used as an additive or modifier in chromatography. It is effective in eluting strongly adsorbed proteins in thiophilic interaction chromatography.

Brij 35 markedly enhances the fluorescence of various dyes and compounds with biochemical or pharmaceutical importance. It is also applied as additive in enzyme assays and in chemiluminescence analysis. 

Brij is a registered trademark of the CRODA International Plc.
