Anion Exchange

TSKgel Anion Exchange Chromatography Columns

Very efficient chromatography can be achieved with the nonporous 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 Super Q-5PW columns.

TSKgel DEAE-NPR nonporous columns are used for the high speed separation and analysis of proteins and poly and oligonucleotides. Applications for the TSKgel DNA-NPR nonporous 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.
