Non-Ionic Biodetergents

Non-ionic detergents contain uncharged, hydrophilic head groups that consist of eithermicellepolyoxyethylene moieties as in TWEEN and TRITON or glycosidic groups as in octyl glucoside and dodecyl maltoside. In general, non-ionic detergents are better suited for breaking lipid-lipid and lipid-protein interactions than protein-protein interactions. Hence, they are considered non-denaturant and are widely used in the isolation of membrane proteins in their biologically active form.

The use and performance of a detergent is dependent on a number of general properties such as hydrophobicity, CMC, aggregation number, charge etc. (TABLE-1 : Properties of Non-Ionic Detergents).

Several investigators have reported problems associated with aldehyde and peroxide impurities in polyoxyethylene detergents 5,6,8. There has also been documented evidence of support of microbial growth and toxic metabolite production in non sterilized aqueous solutions of these detergents.

Our product line of Highly purified, Sterile, 10% aqueous solutions of detergents should offer a definite advantage to those working with sensitive membrane-bound proteins.

Stability/Storage/Handling: This product is sterile & stable for 2+ years as supplied. Store in a cool dry place. Protect from light.
