Chinapeptides Tech's ion exchange chromatography media were prepared by monodisperse, highly crosslinked polyacrylate microspheres. Compared to the traditional agarose based ion exchange chromatography media, Chinapeptides Tech's ion exchange chromatography media have higher mechanical stability and low back pressure. The porous hydrophilic ion exchange media are produced by first forming a hydrophilic layer on the microspheres. Then, ion exchange functional groups are attached onto the hydrophilic layer. Chinapeptides Tech's ion exchange chromatography media are ideal for laboratory and process scale purification of proteins, peptides, nucleic acids, antibiotics, and low molecular weight pharmaceuticals.。
