Summary of the Invention The present invention provides, in a general sense, a new labeling strategy that utilizes 99m Tc chelated with ethylenedicysteine (EC). EC conjugates to various ligands and chelates with 99m Tc for use as an imaging agent for tissue-specific diseases. The drug conjugates of the present invention can also be used as diagnostic tools or as tools for delivering medicaments to specific sites within the mammalian body. Kits for use in imaging tissue-specific diseases are also provided. |
