Abstract: Pentadentate chelators (PDC) resins are the metal chelate resins capable of forming the octahedral complexes with several polyvalent metal ions including Cu2+, Ni2+, Zn2+ and Co2+ with five coordination sites occupied by the chelator. This results in the best stability of the complexes and in one coordination site free for interaction and selective binding of accessible cysteine/histidine residues and chiefly histidine containing biomolecules such as proteins or peptides etc. Cu-PDC can be used as concentration resins to reduce the volume of a protein solution. It can be used also as a universal support for immobilizing covalently all proteins, using a soluble carbodiimide.
