FPG precursor

[18F]FPG is a novel 18F-prosthetic group that can be used to conjugate biomolecules under mild conditions.[1] After 18F-labelling and oxidation of the FPG precursor, the resulting 4-[18F]fluorophenylglyoxal can be selectively coupled with the guanidinium moiety of arginine residues of peptides and proteins. This new bioconjugation reagent offers an efficient access to new protein-based PET radiopharmaceuticals.
