WorkBeads 40S

WorkBeads™ 40S resin for ion exchange chromatography is designed for research and industrial scale purification of proteins, peptides and oligonucleotides by utilizing the difference in their surface charge. WorkBeads 40S resin is a strong cation exchanger derivatized with sulfonate ligands while its contrary WorkBeads 40Q is a strong anion exchanger derivatized with quarternary amines. These resins demonstrate the property of high-resolution separation while giving low backpressure facilitate both capture and polishing purification applications in standard bioprocess columns.

  • High throughput and purity.
  • Reliable and reproducible results.
  • High chemical stability for easy cleaning-in-place.


WorkBeads 40S is an agarose-based chromatographic resin manufactured using a proprietary method that results in porous beads with a tight size distribution and exceptional mechanical stability. Agarose based matrices have been successfully used for decades in biotechnology purification, from research to production scale, due to their exceptional compatibility with biomolecules including proteins, peptides, nucleic acids and carbohydrates. WorkBeads resins are designed for separations requiring optimal capacity and purity. WorkBeads 40S is a strong cation exchanger derivatized with sulfonate as functional groups.
