Analyses of the laser-irradiated keratoepithelin peptide fibrils by reversed-phase HPLC and mass spectrometry. A and B, elution profiles of C110–131 (A) and H110–131 (B) fibrils without laser irradiation (dotted line) or after laser irradiation (solid line) monitored by reversed-phase HPLC. Keratoepithelin peptide fibrils dissolved in dimethyl sulfoxide were injected. C–F, mass spectra of C110–131 (C and D) and H110–131 (E and F) fibrils without laser irradiation (C and E) or after laser irradiation (D and F). For all of A–G, the irradiation period was 24 h.
