WorkBeads™ 100Q resin for ion exchange chromatography is designed for industrial purification applications, which have high flow rate and low back pressure requirements. The product is intended for the purification of proteins, peptides and oligonucleotides by utilizing the difference in surface charge. WorkBeads 100Q is a strong anion exchanger.

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



WorkBeads 100Q 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 100S is a strong anion exchanger derivatized with quaternary amine ligands.
