WorkBeads™ 40/1000 ACT

Agarose-based resin for chromatography
WorkBeads™ 40/1000 ACT and WorkBeads 40/10 000 ACT are pre-activated resins
that enable easy and reliable coupling of proteins, peptides and low-molecular weight
substances for the preparation of customized chromatography resins or enzyme reactors.
The bromohydrin active group reacts with thiol, amino and hydroxyl groups.
Two different resin porosities are available to facilitate optimized coupling of ligands of
different sizes, or to optimize the prepared affinity resin for target molecules of different sizes.
• Easy and reliable coupling procedure
• Stable covalent linkage
• Suitable for coupling of ligands containing thiol, amino and hydroxyl groups​



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,
from research to production scale purification, due to their exceptional compatibility with
biomolecules including proteins, peptides, nucleic acids and carbohydrates.


WorkBeads resins are designed for separations that require optimal capacity and purity.
WorkBeads 40/1000 ACT and WorkBeads 40/10 000 ACT pre-activated resins are
a reliable starting material for the preparation of customized chromatography resins.​

1. The median particle size of the cumulative volume distribution.
2. Avoid substances containing thiol and amino groups.
Substances containing hydroxyl groups will only react if deprotonated.

The unreacted resin is generally stable in alcohols at neutral pH.
3. Agarose matrix and linker. Stability of the coupled substance may differ.
4. The choice of storage conditions for the coupled resin depends on the nature of the ligand.​
