Large Scale POROS bulk chromatography resins
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 resolution, dynamic binding capacity, and capture efficiency over a range of flow rates and are primarily used in polish applications.

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