  • Patent number: 10537650
    Abstract: The invention relates to novel multi-modality probes for imaging, tracking and analyzing stem cells and related biological samples, and methods of preparation and use thereof. The molecular probes of the invention are constructed, for example, by utilizing (a) the high selectivity of long hydrocarbon chains for binding to plasma membranes of cells, (b) a near-infrared (NIR) dye for optical imaging, and (c) a radionuclide for PET or SPECT imaging. The in vitro and in vivo data of the optical and radiolabeled probes demonstrated their utility for detecting the presence of stem cells with multiple imaging modalities.

  • Patent number: 9211349
    Abstract: Embodiments provide dual modality probes for imaging phosphatidylserine (PS) exposure and other anionic membrane surfaces. In various embodiments, the probes were constructed by utilizing a) the high selectivity of synthetic zinc (II) dipicolylamine coordination complexes (Zn-DPA) for targeting externalized PS which over-expresses in apoptotic and necrotic cells, b) a near-infrared (NIR) dye for optical imaging, and c) a widely used clinically approved radionuclide for PET (or SPECT) imaging. A variety of linking elements were incorporated into the probes between the Zn-DPA and radionuclide motif to modulate the pharmacokinetics. The in vitro and in vivo data of radiolabeled dipicolylamine probes demonstrated their utilities for imaging PS exposure with multiple imaging modalities.

  • Patent number: 5177192
    Abstract: Methods for rapidly labeling sulfhydryl-containing antibodies or fragments with technetium or rhenium radioisotopes are disclosed. The method generally involves combining an aqueous mixture of the radiometal in an oxidized form, a reducing agent and a water-soluble polyhydroxycarbonylic acid ligand to form a stable complex of the radiometal in its reduced state and contacting the mixture with the sulfhydryl-containing antibody or fragment to produce a radiometal-labeled antibody or fragment.
