<p>Metal chelates and therapeutic or diagnostic conjugates of site-specific compounds, metal chelates, and metal ions are described. The metal chelates consist of at least two molecular components linked together. One molecular component is a chelate having a high affinity for metal ions and a high Ks value. The other molecular component is a chelate having a low Ks value and the ability to undergo rapid metal exchange.</p> |
