Pretargeted imaging using bioorthogonal chemistry in mice
Current Opinion in Chemical Biology, 2014Following the successful application of in vivo chemistry in chemical biology there has been growing interest in extending the application scope to non-invasive molecular imaging and therapy in living animals and eventually humans. A typical example of such an application is pretargeted radioimmuno-imaging and -therapy: the tumor targeting of a tagged ...

Recent Advances in Pretargeted Imaging of Tumors in Vivo
Analysis & Sensing, 2022AbstractOver the past decades, the pretargeted strategy has emerged as a promising approach to improve delivery of nucleotides into tumor tissues for nuclear imaging and/or therapy. Unlike conventional nuclear imaging and therapy, in which a radiolabeled tumor targeting vector (e.

Evaluation of Tetrazine Tracers for Pretargeted Imaging within the Central Nervous System
Bioconjugate Chemistry, 2023The pretargeting approach separates the biological half-life of an antibody from the physical half-life of the radioisotope label, providing a strategy for reducing the radiation burden. A widely explored pretargeting approach makes use of the bioorthogonal click reaction between tetrazines (Tzs) and trans-cyclooctenes (TCOs), combining the targeting ...

Melanoma imaging with pretargeted bivalent bacteriophage.
Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 2007Random bacteriophage (phage) display peptide libraries have traditionally been used for the selection of clones that bind specific tissues, tumors, and antigens. However, once the targeting peptide is synthetically produced, it often displays a lower affinity than the original phage because of a lack of avidity effects and removal from the virion ...

Signal amplification in molecular imaging by pretargeting a multivalent, bispecific antibody
Nature Medicine, 2005Here we describe molecular imaging of cancer using signal amplification of a radiotracer in situ by pretargeting a multivalent, bispecific antibody to carcinoembryonic antigen (CEA), which subsequently also captures a radioactive hapten-peptide. Human colon cancer xenografts as small as approximately 0.15 g were disclosed in nude mice within 1 h of ...
