Application Note: Extending the Lifetime of GORE® Protein Capture Devices through Alternative Cycling Parameters
Technical Information, 147.61 KB
This evaluation demonstrates a method to extend the lifetime of a GORE Protein Capture Device from 20 to 50 cycles while maintaining capacity as assessed by Dynamic Binding Capacity (DBC) at 10% breakthrough, yield, and purity.
Traditional affinity chromatography technology has not kept pace with increased titers and other upstream process improvements, leading to bottlenecks and lower productivity in downstream protein A purification. To shorten processing times, traditional resin-based protein A is often over-sized or underutilized – simply to keep up.*
Increase productivity: GORE Protein Capture Devices with Protein A utilize a unique membrane solution that provides a binding capacity advantage at high flow rates and improves the speed of purification versus traditional protein A resin technologies. Compare our Dynamic Binding Capacity (DBC) to that of agarose bead-based columns:
GORE Protein Capture Devices are approximately 6–10x faster than traditional (agarose bead-based) chromatography methods, which operate at typical residence times of 3–5 minutes (180–300 seconds).
Designed for affinity purification in early drug discovery screening, late stage optimization, process development, and clinical applications for
- monoclonal antibodies (mAbs)
- next-generation molecules that utilize the Fc region for Protein A binding
The columns are compatible with standard chromatography systems.

GORE Protein Capture Devices with immobilized Protein A* can improve throughput and yields in downstream purification by reducing overall process time through a combination of increased binding capacity and fast flow rates. These pre-packed columns use a unique ePTFE membrane that offers high dynamic binding capacity at short residence time. Designed to increase the efficiency of protein A column purification processes, the 58 mL – 232 mL Devices accommodate rapid cycle capability at low pressure drop, along with demonstrated ability to withstand multiple cleaning cycles. This increased productivity offers researchers the potential for a faster path to clinical trials.

*recombinant Protein A
The GORE Protein Capture Device scales across sizes without compromising binding capacity or speed to quickly and effectively capture antibodies as shown in this overlay of a 1 mL, 9 mL and 58 mL bind-elute curve.
The GORE Protein Capture Devices with Protein A can streamline antibody purification processes because they incorporate a proprietary ePTFE membrane composite.
Unlike traditional support matrices, the composite membrane bed maintains a linear relationship between pressure drop and a wide range of flow rates. Because this unique structure remains stable, the membrane bed is not vulnerable to collapse, channeling or alteration of the bed.
