ABSTRACT:
This invention relates to radiolabeled peptides and methods for producing such peptides. Specifically, the invention relates to technetium-99m (Tc-99m) labeled leukocyte-binding peptides, methods and kits for making such peptides, and methods for using such peptides to image sites of infection and inflammation in a mammalian body.
