Mustang® XT Acrodisc® Ion Exchange Chromatography Units for Laboratory Use and Process Development

Disposable Membrane Chromatography Units for Scale-down Process Development

Fast, easy-to-use, scale-down Mustang membrane unit facilitates process development work.

• Device volume of < 1 mL minimizes sample volume requirements.
• 16 layers of Mustang membrane allows easy scale-up to Mustang membrane pilot- and process-scale capsules.
• Units achieve flow rates of up to 10 membrane volumes per minute (MV) without affecting performance.

Female luer lock inlet and outlet simplifies use with typical low pressure chromatography systems. Disposable 25 mm units. Available in Q and S chemistries.

Mustang Membrane Technology

Mustang XT Acrodisc units, available in Q and S chemistries, are ideal for scale-down process development work in a variety of downstream process applications. A membrane volume of < 1 mL reduces the amount of sample required for evaluation, and the female luer lock inlet and outlet simplifies connection to typical low pressure chromatography systems. The open pore structure eliminates diffusion limitations of conventional macroporous sorbents, allowing biomolecules to access all binding sites by convective flow. In addition, the large pores eliminate the size exclusion effect allowing full access to the binding chemistry for very large proteins, plasmids and viruses.

Each unit contains 16 layers of Mustang membrane, exactly the same as the larger Mustang units, allowing accurate scale-up from process development to pilot and process scale, especially with regards to flow/differential pressure and dynamic binding capacity.

*Note on Optimization: The yield is contingent on flow rate, surface charge, type and concentration of protein, pH, ionic strength, and other components of the sample solution. For connection to typical low pressure chromatography systems, a male luer to 10-32 female connector, such as Upchurch part number P-656, is recommended.

Chromatography Performance

In many applications, the dynamic binding capacity of Mustang Q and S membrane is equivalent to or greater than the equivalent sorbent chemistries. Unlike sorbents, the dynamic binding capacity is independent of flow rate. In polishing applications, for the removal of low levels of contaminants, this means high flow rates (more than 10 MV/min) and low pressure drops that can be fully exploited with minimum membrane volume. In capture applications, good resolution with high yields and minimal elution volumes are achieved, due also to the characteristics of the membrane, the uniform flow path and the very low holdup-volume-to-membrane-volume ratio.

The following charts and chromatograms demonstrate the high resolution and high dynamic binding capacities of the Mustang membrane chromatography units.
