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%.

Purification of Oligonucleotides on TOYOPEARL GigaCap® Q-650S
May 28, 2013

TOYOPEARL GigaCap Q-650S is capable of delivering oligonucleotides of comparable purity to that seen with the TSKgel® SuperQ-5PW (20) resin and at slightly higher process yields under the same loading conditions but at lower pressures.

TOYOPEARL GigaCap® DEAE-650M Preserving Resolution at Increased Protein Loads
April 30, 2013

TOYOPEARL GigaCap DEAE-650M, a very high capacity anion exchange resin for process scale chromatography, offers chromatographers a combination of binding capacities greater than 150 g/L while maintaining peak resolution.

Very High Capacity Cation Exchange Resin
June 2, 2007

A new, very high capacity cation exchange resin* for process scale applications was developed by the researchers at Tosoh Corporation. This resin, with dynamic binding capacities approaching 145 mg/mL for IgG molecules, is the newest member of the Toyopearl product line.
