Affinity Proteins and Resins

Affinity proteins are an invaluable tool in biotechnology and molecular biology research, and can be used in a wide range of applications such as bioseparations, detection, and proteomics analysis. Affinity chromatography takes advantage of the reversible binding interaction between an immobilized ligand and one or more molecules in a sample for one-step purification of the molecule of interest. Purification of recombinant fusion proteins is the most common use of affinity chromatography. Ni-NTA resins bind to histidine tags on recombinant proteins during purification. Protein A, Protein G and Protein L bind immunoglobulins, providing facile purification of antibodies. These proteins can also be used as immunological reagents in a broad range of studies that involve detection of antibody-secreting cells.
