Ion Exchange


- Anion Exchange Column
- Cation Exchange Column
Ion Exchange Chromatography

Tosoh Bioscience offers a broad line of high efficiency columnsfor analysis and isolation of biomolecules by ion exchange chromatography.

For Anion as well as Cation ExchangeChromatography, the product line contains methacrylate-based and silica-based columns for the analysis of proteins, peptides, DNA- andRNA- derived oligonucleotides and other nucleic acid fragments.

Polystyrene-based ion exchange columns are available for analyzing low MW sugars, amino acids, nucleic acid bases, and small drug candidates.

Hydrophilic polymer-based, exchange columns packed with non-porous resin particles are available for the separation of proteins, protein aggregates, charge isomers of monoclonal antibodies, PEGylated proteins, DNA fragments, nucleic acids, oligo DNA, and siRNA.

Specialty columns are available for organic acids by ion-exclusion (OApak-A and SCX) and mono- and disaccharides (Sugar AXI and Sugar AXG).
