Molecular formula : MW : CAS :
nature : Aperture different crosslinked polymer gel for column fillers, polymer volume and low molecular weight substances separate process. The polymer gel a certain aperture size, a low molecular weight substances soak gel, mixed solution adopted, low molecular weight substances because of their small size would be passed, and high molecular weight substances were kept in the gel column, which has resulted in separation of the two substances. The gel is used sephadex.
