WorkBeads™ 40Q

Agarose-based resin for chromatography

The WorkBeads™ 40 S and WorkBeads 40 Q resins for ion exchange chromatography are designed for research

and industrial scale purification of proteins, peptides and oligonucleotides by utilizing the difference in their surface charge.

WorkBeads 40 S resin is a strong cation exchanger derivatized with sulfonate ligands, and WorkBeads 40 Q resin

is a strong anion exchanger derivatized with quaternary amine ligands.

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.



Resin description

WorkBeads are agarose-based chromatographic resins 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 40 S is a strong cation exchange resin derivatized with sulfonates as functional groups.

WorkBeads 40 Q is a strong anion exchanger derivatized with quarternary amines as functional groups.
