The TSKgel DEAE-NPR column is packed with 2.5 µm, nonporous, hydrophilic polymer beads which are surface modified with a weak anion exchange group. These columns are used for the high speed separation and analysis of proteins and poly- and oligonucleotides. TSKgel DEAE-NPR columns are particularly useful for high resolution separation of DNA digests or fragments.
