UniDEAE-50XS Weak Anion Exchange Chromatography Resin
NanoMicro UniDEAE-50XS weak anion exchange chromatography resin features a polymer matrix that has been surface-modified with hydrophilic groups before coupling with ion exchange ligands. 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-50XS utilizes hydrophilic surface modification, offering low non-specific adsorption, high resolution for small molecules, and high binding capacity. Key technical specifications are listed below:
