It requires peptides or proteins carrying isotope-labeled backbone carbonyl positions and a vibrational spectroscopy workflow to read them out. The abstract does not specify exact isotopes or preparation methods.; requires introduction of isotope-labelled carbonyl groups into the peptide backbone; requires compatible vibrational spectroscopy readout
The abstract does not claim that isotope labeling alone resolves all mechanistic details of aggregation or replaces broader structural characterization.
