Find the best tools for your workflow from our broad selection of resins and formats for the purification of proteins and antibodies, or create a customized purification solution by covalent attachment of a ligand to one of our activated supports.
Our prepared and activated magnetic beads, magnetic agarose beads, standard and Superflow agarose resins, POROS™ resins, and other chromatography media enable protein purification at nearly any scale: assay, screening, batch, pilot, or process. In addition, we’ve developed a range of accessory products for all aspects of purification, including disposable columns and binding and elution buffers.
Features of our purification resins
- Broad product selection—prepared affinity and ion exchange supports for the purification and enrichment of proteins and antibodies, as well as activated supports for custom ligand immobilization
- More formats—magnetic beads, 96-well filter plates, loose resins, spin columns and kits, and FPLC cartridges to facilitate screening and other small-scale experiments, as well as process-scale purification
- High performance—resins designed to maximize protein yield and reduce background
- Economical—pricing that is similar to or better than our leading competitors

Featured protein purification categories
We offer strong cation exchange (SCX) and strong anion exchange (SAX) resins and membranes. Our ion exchange (IEX) resins are rigid polymeric beads with covalent surface chemistries, which enable easier handling and packing while offering superior physical and chemical stability.
We offer multiple formats and pack sizes of Protein A, Protein G, Protein A/G, and Protein L immobilized resins that have specific affinity to immunoglobulins, allowing purification of all antibodies of a particular target class regardless of antigen specificity.
We offer a broad range affinity purification products designed for the purification of recombinant proteins—specifically cobalt and nickel ion-metal affinity chromatography (IMAC) resins for His-tagged proteins and immobilized glutathione resins for GST-tagged proteins. Small-scale resins are also available for c-myc and HA-tagged proteins.
The strong association between avidin and biotin has been successfully employed in various affinity purification schemes. We offer a variety of immobilized biotin binding supports, including avidin, streptavidin, NeutrAvidin protein, CaptAvidin™, and monomeric avidin resins.
We offer kits in a range of formats for various immunoprecipitation (IP) and co-immunoprecipitation (co-IP) strategies, as well as products for capturing protein-nucleic acid interactions (ChIP and RIP) and solutions for enriching recombinant or modified proteins (pull-down assays).
Pipette tip-based, ready-to-use MSIA™ microcolumns enable affinity purification of very small quantities of target analytes from complex biological samples. Use robotics-ready MSIA microcolumns to immunoprecipitate and purify cleaner analytes with enhanced reproducibility.
Protein enrichment strategies involve the selective isolation of protein subclasses sharing a common posttranslational modification (PTM), such as phosphorylation and glycosylation, typically via affinity ligands such as ion-metal affinity chromatography (IMAC) or immobilized lectins.
We’ve developed activated supports for the immobilization of proteins and other molecules for target-specific affinity purification. The functional groups on the resins utilize a range of coupling mechanism for immobilizing amine-, sulfhydryl-, carbonyl-, and carboxyl-based targets.
For your convenience, we offer a wide range of disposable plastic columns (spin- and gravity-based) for small-scale purification needs, BupH™ Dry-Blend Buffer Packs, and Pierce™ 10X and 20X Concentrated Buffers.
When you need high performance and high throughput on a large scale, POROS bulk chromatography resins are the industry standard for process-scale bioseparations.
Mini- and microcentrifuges to accelerate your protein preparation protocols with RCFs up to 21,000 x g in compact, safe, easy-to-use instruments.
Designed for solid performance and consistent results, our benchtop centrifuges deliver efficient sample processing for your protein purification & isolation applications.
