Hydrogel analysis of P 11 -13/P 11 -14. A) Hydrogel formed upon equimolar mixing of P11-13 and P11-14(K) indicated by arrow. B and C) Transmission electron microscopy (TEM) images of self-assembled B) P11-4 at pH 2 and C) P11-13/P11-14(K). D) Circular dichroism analysis of P11-4, P11-13 and P11-14(K) unimers, and P11-4 and P11-13/P11-14(K) hydrogels at pH 7.4. Random coil conformation is observed for peptide unimers while a β-sheet conformation is observed for peptide hydrogels.
