GORE Protein Capture Devices with Protein A
Manufacturer: Gore (日本ゴア)
Made in Japan
Model: Protein Capture
Overview of Protein Capture
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.
GORE Protein Capture Devices in 1.0 mL, 3.5 mL, 9 mL, 58 mL, 116 mL, 232 mL, 250 mL, 500 mL and 1L sizes.
A cost-efficient platform for antibody production with comparable product quality to existing technologies. A flexible platform for single use manufacturing.
Representative dynamic binding capacity demonstrated with a 9 mL 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) chromatography methods, which operate 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, clinical and routine bioprocessing 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 through a combination of increased binding capacity and fast flow rates. These pre-packed columns use a unique membrane that offers high dynamic binding capacity at short residence time. Designed to increase the efficiency of protein A column purification processes, the 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.

Technology
The GORE Protein Capture Devices with Protein A can streamline antibody purification processes because they incorporate a proprietary 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.
