UniDEAE-30S Weak Anion Exchange Chromatography Resin
NanoMicro UniDEAE-30S weak anion exchange chromatography resin features a polymer matrix that is surface-modified with hydrophilic groups before ion exchange ligands are coupled. This design provides excellent biocompatibility and physicochemical stability for bioactive macromolecules, significantly improving purification efficiency. It is ideally suited for the purification of small biomolecules such as small proteins, peptides, nucleic acids, and antibiotics.
UniDEAE-30S utilizes a hydrophilic surface modification, offering low non-specific binding, high resolution for small molecules, and high binding capacity. Key technical parameters are listed below:
