Hydrophobic Interaction Chromatography: Effects of Mixed Electrolytes on Protein Separations
January 28, 2014

For HIC separations, parameters other than resin surface modifications can be employed to enhance performance. This application note addresses the electrolyte composition of the mobile phase as one parameter responsible for protein adsorption and desorption. The results presented illustrate the benefits regarding capacity and selectivity in HIC of often neglected salts and their mixtures.

Monoclonal Antibody Purification with a High Capacity Protein A Resin
November 26, 2013

Protein A resins constitute a substantial cost in state-of-the-art mAb purification processes. Factors such as operating cycles, capacity, and mAb titer can have an impact on total costs associated with mAb purification. The purification of a monoclonal antibody from crude feed stock using TOYOPEARL? AF-rProtein A HC-650F, a high capacity protein A resin from Tosoh Bioscience, show that this particular high capacity protein A resin delivers highly pure antibodies at yields approaching 90%.
