Proteus Detergent Anion Exchange (DetEx) Mini Spin Columns designed for rapid and effective removal of free detergents micelles and complete detergent exchange.  Optimized for membrane proteins with pI<8 in complex with non-ionic or zwitterionic detergents.

Simple and adaptable to your protein requiring only a micofuge for operation.  Faster and more effective than other methods of detergent removal or exchange such as chromatography (hydrophobic adsorption, ion exchange, affinity, gel filtration), dialysis and precipitation. 

Ideal for applications such as ELISA, IEF, MS and NMR which suffer from interference with excess detergents.

Weak Anion Exchanger for binding membrane proteins with pI<8

Complete detergent exchange/removal

Column bed volume: 0.2 ml

Max sample loading volume: 0.4 ml

Typical protein binding capacity: 2 mg

Elution in a small volume (minimum volume 50 μl)

Universal appeal as most proteins have a pI between 4-8

Rapid removal and exchange of free detergent micelles in 10 min

Generate concentrated protein free of detergent micelles

Only requires a microfuge for use
