    摘要: The present invention relates to dimeric pentadentate chelators with exceptionally strong binding of metal ions, for detection, immobilization and purification of biomolecules. Dimeric chelators offer a cooperativity of binding of two adjacent immobilized metal ions simultaneously to a histidine-tagged biomolecule, which gives advantageous properties regarding strength of binding compared to a corresponding monomer chelator. In addition, a dimer increases the selectivity (ease of separation) against non-tagged biomolecules with low metal-ion affinity.The dimeric pentadentate chelator according to the invention has the following general formula: whereinSc is a scaffold or a connecting structure that contains at least two functional groups enabling coupling of two pentadentate chelators (PD), andPD is a pentadentate chelator having the formula:
