Affinity Chromatography Media 
  
    |  ChinaPeptides Tech’s affinity chromatography media were prepared by monodisperse, ly crosslinked polyacrylate microspheres. The affinity chromatography media are produced by first forming a hydrophilic layer on the microspheres. Then, nickel ion (Ni2+) functional groups are chelated onto the hydrophilic layer.  ChinaPeptides Tech’s affinity chromatography media have  selectivity in separation of histidine labeled proteins.
