Modular strategies for PET imaging agents Hooker JMCurr Opin Chem Biol 2010[Feb]; 14 (1): 105-11In recent years, modular and simplified chemical and biological strategies have been developed for the synthesis and implementation of positron emission tomography (PET) radiotracers. New developments in bioconjugation and synthetic methodologies, in combination with advances in macromolecular delivery systems and gene-expression imaging, reflect a need to reduce radiosynthesis burden in order to accelerate imaging agent development. These new approaches, which are often mindful of existing infrastructure and available resources, are anticipated to provide a more approachable entry point for researchers interested in using PET to translate in vitro research to in vivo imaging.|Drug Delivery Systems[MESH]|Gene Expression[MESH]|Peptides/chemistry[MESH]|Positron-Emission Tomography/*methods[MESH]|Proteins/chemistry[MESH]|Radiopharmaceuticals/*chemistry[MESH] |
