TSKgel® Anion Exchange Chromatography Columns

Very efficient chromatography can be achieved with the non-porous TSKgel® STAT columns due to the novel bonding chemistry and the absence of micro-pores. Applications for the TSKgel® Q-STAT columns include the separation of: proteins, peptides, low molecular weight nucleic acids, aggregates and charge isomers of monoclonal antibodies, PEGylated proteins, oligo DNA, and siRNA. The TSKgel® DNA-STAT column is ideal for the analysis of DNA fragments, nucleic acids and nucleotides.

The pore structure and bonding chemistry of TSKgel® BioAssist Q columns provides high capacity for small to very large molar mass proteins and nucleic acids.

Proteins, peptides, DNA and RNA-derived oligonucleotides, and other nucleic acid fragments are typical samples that are analyzed or isolated on the TSKgel® DEAE-5PW and TSKgel® SuperQ-5PW columns.

TSKgel® DEAE-NPR (non-porous resin) columns are used for the high speed separation and analysis of proteins and poly and oligonucleotides. Applications for the TSKgel® DNA-NPR (non-porous resin) columns include the high efficiency separation of DNA fragments, PCR products, or plasmids.

TSKgel® DEAE-2SW and TSKgel® QAE-2SW (both 5 µm, 12.5 nm) and TSKgel® DEAE-3SW (10 µm, 25 nm) are available for analyzing smaller molar mass samples such as nucleotides, drug candidates, catecholamines, and small peptides or proteins.

TSKgel® Sugar AXG columns are packed with 10 µm beads and are used for the gradient separation and analysis of monosaccharides, disaccharides, and sugar alcohols.

For isocratic separation of carbohydrates where lower and constant back pressures may be generated, the 8 µm TSKgel® Sugar AXI column is optimal.

TSKgel® SAX columns are used for the separation of isomerized sugars, alcohols, and low molar mass organic acids.
