Abstract

Purification of poly-amino acid-tagged recombinant proteins has been improved by the use of a carboxymethylated aspartate ligand complexed with a third-block transition metal having an oxidation state of 2+ and a coordination number of 6. A method for synthesizing the metal ion-CM-Asp complex is also described. Further, the metal ion-CM-Asp complex can be used for screening protein function.
