Overview

GORE Protein Capture Devices in 1.0 mL, 3.5 mL, 9 mL, 58 mL, 116 mL, and 232 mL sizes.
Traditional affinity chromatography technology has not kept pace with increased titers and other upstream process improvements, leading to bottlenecks and lower productivity in downstream purification. To gain flow and 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 technologies. Compare our Dynamic Binding Capacity (DBC) to that of agarose bead-based columns:

Representative dynamic binding capacity of the 9.0mL GORE Device (PROA103) versus a standard agarose bead-based technology, using a purified monoclonal antibody.
GORE Protein Capture Devices are approximately 6-10x faster than traditional agarose bead-based technology which operates at typical residence times of 3–5 minutes (180–300 seconds).
Applications

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.

Performance
GORE Protein Capture Devices with immobilized Protein A* can improve throughput and yields in downstream purification by reducing overall process time. These pre-packed columns use a unique ePTFE membrane that offers high dynamic binding capacity at short residence time. The 58 mL - 232 mL 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.

Technology
The GORE Protein Capture Device can streamline antibody purification processes because it incorporates 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.
