ESI mass spectra of the α5β1-targeting peptides (α5β1 L). (A) The linear form of the α5β1-targeting peptide (GGCRRETAWAC) exhibits an intense peak at 1208.9 Da. (B) By contrast, the cyclic form of the α5β1-targeting peptide (cGG*CRRETAWAC*) exhibits an intense peak at 1206.6 Da. This result indicates that the linear profile has been modified by dehydrogenization between two cystine residues to create the cyclic form.
