Application Note: Prediction of the impact of buffer type with mechanistic simulation

Application to protein purification by IEX chromatography

  • by Ypso-Facto
  • January 15, 2024
The proper selection of buffers is essential in the design of ion exchange processes. It was reported that at a given pH and ionic strength, a change in the type of buffer (e.g., acetate to phosphate) may have a dramatic impact on protein separation. This study aims at assessing whether mechanistic...
