Dextran-Based Ion Exchange Resins for High-Capacity, Gentle Biomolecule Purification

Ion Exchange Chromatography with Zetadex: Dry and Pre-Hydrated Formats for Reliable Protein and Nucleic Acid Separation

Zetadex ion exchange resins are cross-linked dextran matrices functionalized for strong or weak anion and cation exchange. Designed for charge-based purification of proteins and nucleic acids, they are available as dry powders or ready-to-use hydrated formats—supporting scalable workflows from lab to process with high binding capacity and low nonspecific adsorption.

Dry

Ideal for labs requiring flexible formulation and extended shelf life. These dry dextran-based ion exchange resins allow for customizable buffer preparation and optimized storage stability.
