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.*

GORE Protein Capture Devices with Protein A utilizes 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:
Dynamic binding capacity of the 9.0mL GORE Device (PROA103) versus a standard agarose bead- based technology, using a purified monoclonal antibody.
Alleviate the purification bottleneck: The new 9.0mL Device (PROA103) utilizes ePTFE membrane technology to provide performance advantages over traditional agarose resin columns in early process development.
Example dynamic binding capacity of the GORE Device (PROA101) versus a standard agarose bead- based technology, using a purified polyclonal human IgG.
Increase productivity: Gore’s 1.0mL Device (PROA101) captures greater than or equal to 30mgs/mL at 20 seconds residence time, approximately 10x faster than traditional agarose bead based technology at typical residence times.
Applications
Designed for affinity purification in early drug discovery screening, late stage optimization, and process development 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 offer high dynamic binding capacity at short residence time, along with demonstrated ability to withstand multiple cleaning cycles. This increased productivity offers researchers the potential for a faster path to clinical trials.
| PROA101 (1.0mL) | PROA103 (9.0mL) | |
|---|---|---|
| Dynamic binding capacity | ≥ 30 mg/mL | ≥ 40 mg/mL |
| Residence time | 20 seconds | 30 seconds |
| Number of cleaning cycles | 0.2 N NaOH for 3 minutes up to 50 cycles | 0.2 N NaOH for 3 minutes up to 100 cycles |

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.
