Technical challenges associated with the radiolabeling of monoclonal antibodies utilizing short-lived, positron
1Department of Medical Imaging, Memorial Sloan-Kettering Cancer Center, New York, NY 10021.
Abstract:
Many factors, both physical and chemical, affect the radiolabeling of a chemical compound. These factors add a new dimension of complexity when the labeling of monoclonal antibodies is attempted with short-lived, positron emitting radionuclides. A lack of appreciation for the unique chemical separations associated with the radionuclide incorporated into the synthetic precursor can often lead to unexpected or non-reproducible results.
