  • Further, Cellufine MAX ion exchange (IEX) media are made using surface modification techniques that dramatically increase ligand availability, which translates to higher dynamic binding capacities. (amsbio.com)
  • recovery
  • To this end, the ion exchange chromatography recovery of CHO-HBsAg from a recombinant Chinese hamster ovary cell line was shown to increase from about 55 to 80% by the addition of 1% poly(ethylene glycol) (PEG 10,000) to the mobile phase. (diva-portal.org)
  • methods
  • found that while HbS and HbC can statistically affect HbA1c results across the range of testing options, including HPLC ion-exchange chromatography and boronate affinity methods, enzymatic assays, and immunoassays, only ion-exchange HPLC allows the operator to identify the presence of an HbS or C variant.
