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%.
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, 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.
TOYOPEARL GigaCap DEAE-650M is an ideal anion exchange resin for the chromatographic purification of biotherapeutic products. Since the TOYOPEARL GigaCap DEAE-650M has such a high dynamic binding capacity, the need for very large columns and massive buffer consumption is minimized, particularly for proteins expressed at higher levels due to upstream improvements.
TOYOPEARL MX-Trp-650M, a mixed-mode chromatography resin for process scale chromatography, offers chromatographers selectivity and salt tolerance combined with binding capacities that are similar to traditional cation exchange resins.
TOYOPEARL AF-rProtein A-650F was designed for use in mAb purifications. This paper demonstrates the excellent kinetics, superior dynamic binding capacity at very fast flow rates, selectivity and alkaline stability of this resin.
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.
