Chromatography has become an essential tool for the purification of proteins, since most purification schemes involve some forms of this methodology. Recently, using chromatographic matrices prepared from symmetrical aminosquarylium cyanine dyes immobilized on Sepharose via a central alkylamino residue, we were able to isolate lysozyme, α-chymotrypsin and trypsin from a mixture. Following this, we...
The most selective purification method for proteins and other biomolecules is affinity chromatography. This method is based on the unique biological‐based specificity of the biomolecule–ligand interaction and commonly uses biological ligands. However, these ligands may present some drawbacks, mainly because of their cost and lability. Dye‐affinity chromatography overcomes the limitations of biological...
