Affinity Chromatography Resins
Affinity chromatography separates complex mixtures through highly selective biochemical interactions. This widely used purification technology efficiently separates a target molecule from impurities. Our range of affinity resins are designed for high throughput and cost-effective purification, from process development through large-scale manufacturing.

- Data Sheet: Eshmuno® A Resin
Eshmuno® A media is a rigid, high-capacity, acid and alkalineresistant Protein A affinity chromatography media for the purification of Fc-containing proteins, including but not limited to monoclonal antibodies.
- Data Sheet: Eshmuno® P anti-A and anti-B Resins
High performance, acid and alkaline resistant affinity chromatography resins designed for the removal of anti-A and anti-B antibodies from plasma-derived immunoglobulin (Ig).
- Data Sheet: Fractogel®Chromatography Resin
Fractogel® resins consist of synthetic methacrylate based polymeric beads providing excellent pressure stability resulting in high flow rates. Depending on your purification application, we can offer resin sized M-type beads with a particle size of 40–90 μm and small S-type beads with a particle size in the range of 20–40 μm.
- Application Note: Using Ethylene Glycol Emprove® Evolve to increase Eshmuno®
Sodium hydroxide (NaOH) is a standard cleaning agent for protein A chromatography resins. Typically, a concentration of 0.1 mol/L NaOH is used. The inclusion of 20% ethylene glycol in a 0.1 mol/L NaOH cleaning solution increases the lifetime of Eshmuno® A columns significantly.
- Application Note: Detection and Quantification of Leached Protein A from Eshmuno® A Resin Using Cygnus F400 Protein A ELISA Kit
Cygnus Technologies performed the initial feasibility testing of the Eshmuno® A Protein A ligand in the Cygnus Protein A ELISA Kit (Cat# F400). Upon successful completion of the feasibility testing, Cygnus proceeded with quantification of the assay for use in in-process and drug substance samples using the Eshmuno® A Protein A resin.
- User Guide: MiniChrom® Pre-Packed Columns
The MiniChrom® columns are prepacked chromatography columns designed for laboratory-scale process development evaluations. When used for biomolecule separations, the results achieved with MiniChrom® columns are typically similar to those obtained using traditional laboratory-scale columns from different vendors.
