TSK-GEL and Toyopearl Resins for
Oligonucleotide Purifications

The Tosoh Bioscience laboratories recently completed a series of experiments to determine the oligonucleotide dynamic 
binding capacities for Toyopearl and TSK-GEL anion exchange resins. The resin selection table below presents the data 
obtained from these experiments using a 20-mer oligonucleotide with the sequence 5’-GAA TTC ATC GGT TCA GAG AC-3’.

Please note that the TSK-GEL SuperQ-5PW bulk resins are available in 20 and 30µm particle sizes to provide superior r
esolution performance for your “n-1” purifications. Click here

Toyopearl SuperQ-650M resins have the highest capacity shown due to lower crosslinking than the corresponding TSK-GEL resins. 
This lower percentage of crosslinking leaves a higher number of ligand attachment sites available for increased binding capacity.
