This page covers the principles and methods of chromatofocusing, a chromatography technique that separates proteins according to differences in their isoelectric point (pI).
This page clarifies sample preparation, buffer exchange and desalting, removal of lipoproteins, phenol red, and low molecular weight contaminants in Ion exchange chromatography.
How to separate biotin and biotinylated substances by affinity chromatography using HiTrap Streptavidin HP and Streptavidin Sepharose High Performance products from Cytiva.
Antibody Purification using Protein A, Protein G, or Protein L Agarose protocol is designed as a quick purification method for antibodies from mammalian sera, ascites, and cell culture supernatants. It should be noted that if the starting material is serum
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 chromatography media.
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.
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 shows how to purify histidine-tagged recombinant proteins using Ni Sepharose 6 Fast Flow from Cytiva. Ni Sepharose 6 Fast Flow consists of 90 µm beads of highly cross-linked agarose, to which a chelating ligand has been immobilized and
In this section the practical aspect of Reverse Phased Chromatography ( RPC) is discussed including media and column selection and eluent selection and preparation.
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.
This page shows how to perform a separation with a Sephadex LH-20 column from Cytiva which are Size Exclusion Chromatography media of polysaccharide network made from cross-linked hydroxypropylated dextran beads.
This page shows how to separate fibronectin by affinity chromatography using Gelatin SepharosePerforming a Separation of Fibronectin with Gelatin Sepharose® 4B from Cytiva.
Glutathione Sepharose® High Performance is recommended for high-resolution purification of GST-tagged proteins, providing sharp peaks and concentrated eluent.
