Abstract

|
|
|
It is essential use of long term half life radioisotopes for positron emission tomography (PET) imaging study of biopharmaceuticals because most of biopharmaceuticals have long biological half-life. Some representative isotopes are 124I, 64Cu, 89Zr and so on. These PET radioisotopes and their radiopharmaceuticals have recently received growing interest because of long half life and good imaging properties. Furthermore, 64Cu and 89Zr can be used in a number of radiopharmaceuticals due to its ease of conjugation to peptides and antibodies using the proper chelator. In recent years, since 124I was first developed in 2005, we have been studied to develop an efficient method and procedure for producing these radioisotopes, and we have made considerable progress in production of long term half life radioisotopes. This review introduces the general production system, purification procedure, and several advances on targeting method for 124I and 64Cu in KIRAMS.
