Role of Ca2+ in the binding mechanism of EHDP-Tc complex to bone

  • 1. Rijksuniversiteit Leiden (Netherlands). Akademisch Ziekenhuis

Description

Experiments are described testing the hypothesis that 99m-Tc-EHDP complex travels to bone as a unit and dissociates at the bone binding site because of the high affinity of EHDP for hydroxyapatite after which technetium binds separately. The results indicate that technetium is not dissociated from EHDP in binding to hydroxyapatite, but the EHDP-Tc-ligand stays intact. It is postulated that calcium plays an important role in bone-labelling with EHDP-Tc complex and that in fact the EHDP-Ca-Tc complex is the binding agent. Only by assuming the presence of this agent could the action of magnesium-ions or of excess calcium-ions be explained. (Auth./C.F.)
