Ion-exchange PS-DVB Resin

AstraChroma ion-exchange media base on PS-DVB microspheres. It has excellent mechanical property and can withstand pressures up to 10 MPA. 1000Å pore guarantee the free entry and exit of biomacromolecule. It is endowed with enough hydrophilicity by the unique coating technology of Biovanix, while the monodisperse particles effectively reduce column pressure and mass transfer barriers.
AstraChroma lEX media use “tentacle” surface derivation technology, Functional groups are covalently bonded on the substrate surface in the form of linear polymer chains. With a larger number of effective functional groups, its low steric hindrance enables macromolecules, antibodies, viruses, and plasmids to bind more effectively to the functional groups of the media, increasing the binding capacity significantly. “Tentacle” structure effectively reduces the non-specific interaction between biomolecules and media, thus improving the recovery of target molecules.
