Glutathione Sepharose® High Performance is recommended for high-resolution purification of GST-tagged proteins, providing sharp peaks and concentrated eluent.
This page covers the principles and methods of chromatofocusing, a chromatography technique that separates proteins according to differences in their isoelectric point (pI).
Ni Sepharose High Performance consists of highly cross-linked 6% agarose beads (34 µm) to which a chelating group has been immobilized and subsequently charged with Ni2+ ions.
This page clarifies sample preparation, buffer exchange and desalting, removal of lipoproteins, phenol red, and low molecular weight contaminants in Ion exchange chromatography.
Ligands are coupled in a simple one-step procedure in the presence of a coupling reagent, carbodiimide. The carbodiimides may be regarded as anhydrides of urea.
This page shows coupling through the primary amine of a ligand with a NHS-activated Sepharose High Performance, NHS-activated Sepharose 4 Fast Flow and CNBr-activated Sepharose from Cytiva.
GSTrap™ affinity columns are specially designed 1 ml and 5 ml HiTrap® columns packed with Glutathione Sepharose High Performance, Glutathione Sepharose 4 Fast Flow, or Glutathione Sepharose 4B media.
This page covers the use of Sepharose High Performance media for purification of proteins, peptides or oligonucleotides, when to use them, and with which systems.
Superose from Cytiva are Size Exclusion Chromatography media consisting of a composite base matrix of dextran and agarose. This page shows how to perform a separation with a superose column.
The Amberlite™ XAD-4 resin used in Porozorb™ cartridges is a proven technology that is highly effective in removing various detergents from cell culture media for biopharmaceutical applications such as vaccine production.
