Biodistribution studies
Biodistribution is a method of tracking where compounds of interest travel in an experimental animal or human subject. For example, in the development of new compounds for PET (positron emission tomography) scanning, a radioactive isotope is chemically joined with a peptide (subunit of a protein). This particular class of isotopes emits positrons (which are antimatter particles, equal in mass to the electron, but with a positive charge). When ejected from the nucleus, positrons enc… WebJan 31, 2024 · Compared to small molecules, biodistribution shows fundamental to identify target organs, anticipate safety and efficacy, may integrate in safety/pharmacology studies, and may eventually be ...
