WorkBeads 40 TREN

Agarose-based resin for chromatography

WorkBeads™ 40 TREN resin for multimodal Ion Exchange Chromatography (IEX)
has a ligand that is positively charged below approx. pH 9.
The resin can be used for several different applications, e.g., for multimodal IEX,
for sample cleanup in monoclonal antibody (MAb) purification processes
in order to guard the Protein A column from chromatins and other host cell impurities,
or as a polishing step in the MAb purification process.


• Improved selectivities through multimodal IEX separation
• Reduced fouling of Protein A resins by chromatin and host cell impurity removal
• High binding capacity and purity​ 



Resin description
WorkBeads are agarose-based chromatographic resins manufactured using a proprietary method
that results in porous beads with a tight size distribution and high 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 TREN resin contains ligands based on Tris(2-aminoethyl)amine (TAEA).
The structure of the ligand used in WorkBeads 40 TREN is shown in Figure 1.


WorkBeads 40 TREN resin can be used for the separation of biomolecules exploiting surface
charge to purify proteins, peptides and oligonucleotides.
It can also be used in flow through mode to adsorb impurities while letting the target
pass through the column (negative chromatography mode).​


The main characteristics of WorkBeads 40 TREN resin are shown in Table 1.
For more detailed instructions of how to use WorkBeads 40 TREN, see instruction IN 40 600 020.
