Cross-linked dextran the gel filtration resin series are dextran-based gel filtration media, hydrophilic and porous. Used for buffer exchange, desalting, small molecule removal, separation of peptides, oligonucleotides, antibiotics, chemical drugs, natural products, nanomaterial purification, and wastewater treatment. Operates via molecular sieve principle. Types by particle size: cross-linked dextran the gel filtration resin coarse, medium, fine, and superfine.
