Exendin 4 (5-39)amide is a truncated exendin analog with C-terminal amidation to enhance stability. Removal of the initial residues sharpens focus on the central helical domain and receptor-binding motifs. Researchers employ it in structure-activity profiling and folding studies. Its stabilized backbone supports extended biochemical assays.
