VDX Series IEX Resins
VDX Series Products represent Vdo Biotech's premium chromatography resin line with fully independent intellectual property rights. They deliver high performance, reliable selectivity, and cost-efficiency, addressing the market's urgent demand for high-performance bioprocessing consumables.VDX Series ion exchange media are categorized into three lines based on following performance characteristics: High-Resolution, High-Capacity, Strong-Binding.
VDX XQ——High-Capacity Series
VDX XQ is a high-capacity strong anion exchange resin. This chromatography resin significantly enhances the ligand density of quaternary ammonium groups and binding efficiency through special surface modification, making it particularly suitable for the capture of all charged biomolecules including proteins, peptides and nucleic acids.
