When you need high performance and high throughput on a large scale, POROS® bulk chromatography resins are the industry standard for process-scale bioseparations.

Utilized in multiple processes, these breakthrough resins combine optimal particle size and pore structure with a rigid backbone and proprietary chemistries. POROS® 50 µm resins demonstrate exceptionally high dynamic binding capacity, capture efficiency, and resolution over a range of flow rates.

POROS® products are manufactured in a state-of-the-art chromatography resin manufacturing facility and are tested using the highest-quality standards to support use in regulated biotherapeutic markets.

CaptureSelect™ affinity resins offer superior selectivity resulting in higher yields and improved purity in the initial capture step. We are developing numerous products for large scale purification of various biologics such as antibodies and antibody fragments, fusion proteins, hormones and viruses.
