    摘要: A one vial method for labeling a sulfhydryl containing antibody or antibody fragment with technetium-99m is disclosed. The method comprises contacting an antibody mixture comprised of a sulfhydryl containing antibody or antibody fragment and a reducing agent with technetium-99m in an oxidized state. In a preferred embodiment, the antibody mixture further contains a water soluble ligand. A one vial kit for labeling a sulfhydryl containing antibody or antibody fragment with technetium-99m is also disclosed.

    摘要: The invention relates to radiolabeled imaging of a mammalian body. The invention in particular provides for reagents labeled with technetium-99m for such imaging. The invention specifically provides somatostatin, somatostatin derivatives, somatostatin analogues or peptides that bind to the somatostatin receptor and contain at least 2 cysteine residues that form a disulfide or wherein the disulfide is reduced to the sulfhydryl form that are directly labeled with technetium-99m and that can be targeted to specific sites within a mammalian body for imaging.
