Immobilized Metal Chelate Affinity Chromatography (IMAC)
This page shows how to separate proteins and peptides with affinity for metal ions by immobilized metal chelate affinity chromatography using HiTrap Chelating HP, Chelating Sepharose Fast Flow,His MicroSpin Purification Module or HisTrap Kit from Cytiva.
Capto Adhere
Capto adhere from Cytiva is a multimodal strong anion exchanger for BioProcess applications.
Troubleshooting Reversed Phase Chromatography (RPC)
Poor-quality eluent components can cause a phenomenon referred to as “ghosting”. Trace levels of organic impurities bind to the medium, concentrating during equilibration and sample application. When elution begins, these contaminants appear in the chromatogram as unknown, or “ghost” peaks.
Troubleshooting Guide for Affinity Chromatography of Tagged Proteins
This page shows troubleshooting instructions for affinity chromatography of tagged proteins using Cytiva products.
Principles and Standard Conditions for Different Purification Techniques
This page describes principles and standard conditions for different purification techniques of histidine-tagged proteins using Cytiva products.
Affinity Chromatography Troubleshooting
This page shows how to solve practical problems that may occur when running an affinity chromatography column.

LRA (Lipid Removal Agent) for Biopharmaceutical Production
Lipids are naturally-occurring hydrocarbons that are poorly soluble in water and soluble in non-polar solvents such as ether and chloroform.
Purification of Thiol-Containing Substances By Covalent Chromatography
Thiol-containing substances can be isolated selectively by covalent binding to an activated thiolated matrix via thiol-disulphide exchange to form a mixed disulphide bond. After washing away unbound material, the thiol-containing substance is eluted by reducing the disulphide bond. This technique...
