Dextran-Based Chromatography Resins for Size Exclusion and Ion Exchange
Chromatography Resin
Zetadex™ chromatography resins from emp BIOTECH are cross-linked dextran-based matrices designed for efficient size exclusion and ion exchange purification. Offered in both dry and pre-hydrated formats, Zetadex resins are suitable for desalting, buffer exchange, and the separation of proteins, nucleic acids, and other charged biomolecules. With a range of particle sizes and ion exchange functionalities—including DEAE, QAE, and CM—Zetadex supports gravity-flow, spin-column, and preparative applications in research and diagnostic workflows.
The following formats are available
Size Exclusion
For gentle desalting, buffer exchange, and the separation of proteins and nucleic acids.
Dry
Hydrated
