High affinity purification
WebAbstract. Immobilized metal affinity chromatography (IMAC) is a technique primarily used in research and development laboratories to purify proteins containing engineered histidine tags. Although this type of chromatography is commonly used, it can be problematic as differing combinations of resins and metal chelators can result in highly ...

WebThe rigid structure of dilactams provides them with very high affinity to f-elements and high selectivity to An(III) over Ln(III) . The extraction of Am and Eu from 0.03–3 M HNO 3 solution into 1,2-dichloroethane was studied. The distribution ratios increased with increasing aqueous phase acidity. WebAffinity ligands are now coupled to magnetic particles, latex beads, nanoparticles, macro-beads, membranes, microplates, array surfaces, dipsticks and a host of other devices that facilitate the capture of specific biomolecules. Applications of affinity targeting include purification, scavenging (or removal of contaminants), catalysis (or ...
