:sephadex(R) deae A-25 for chromato-graphy
Description:
Sephadex® DEAE A-25 is a dextran-based gel filtration medium commonly used in chromatography for the separation and purification of biomolecules, particularly proteins and nucleic acids. It is characterized by its ability to facilitate ion-exchange chromatography due to the presence of diethylaminoethyl (DEAE) groups, which impart a positive charge to the medium. This allows for the selective binding of negatively charged molecules, such as proteins with acidic isoelectric points. Sephadex® DEAE A-25 has a specific particle size and porosity that enables efficient separation based on molecular size and charge. Its high stability and biocompatibility make it suitable for various applications in biochemical research and industrial processes. The medium is typically used in a buffered aqueous environment, and its performance can be influenced by factors such as pH, ionic strength, and temperature. Overall, Sephadex® DEAE A-25 is a versatile tool in the field of chromatography, providing reliable results in the purification of complex biological mixtures.
