TSKgel DNA-NPR columns are packed with 2.5 micron, non-porous, high efficiency, hydrophilic polymer beads which are surface modified with a weak anion exchanger. Because NPR columns contain non-porous particles, binding capacity is low compared to porous columns with the same ligand functionality.

Column dimensions are optimized for the high efficiency separation of DNA fragments, PCR products, or plasmids. A small guard column is available to protect the analytical column.
