TSKgel Protein A-5PW HPLC columns

TSKgel Protein A-5PW column

This high performance protein A column was designed for fast and accurate IgG titer determination with excellent recovery. Offering 1-2 minutes/analysis and >2000 injections per column, users can accurately monitor the titer of mAb with high confidence.




TSKgel UP-SW3000, 2 µm UHPLC/HPLC columns

Offering dual functionality for use in both UHPLC and HPLC systems, the TSKgel UP-SW3000 column is the new gold standard for mAb characterization.



TOYOPEARL AF-rProtein L-650F resin

TOYOPEARL AF-rProtein L-650F is a protein L resin that exhibits the highest binding capacity for antibody fragments that lack a Fc-portion (e.g. Fab, scFv, Dab, etc.). This resin also has the ability to bind to antibody classes that do not have the affinity to Protein A, such as IgM and IgA.




TOYOPEARL AF-rProtein A HC-650F resin

With demonstrated dynamic binding capacities of >70 g/L at residence times of 5 minutes, TOYOPEARL AF-rProtein A HC-650F was designed to reduce production costs.
