[Azhx]-[Lys(Mca)]-P11-8 – Fluorescent Peptides

The P11-family of peptides comprises over 20 different peptides which self-assemble into β-sheet structures to form self-supporting isotropic hydrogels under physiological conditions (pH 7.4, 140 mM NaCl). Self-assembling peptides of the P11-family undergo one-dimensional self-assembly, forming single molecule thick, micrometer-long β-sheet nanotapes. Further assembly results in the nanotapes stacking in pairs to form ribbons which further assemble to form fibrils, then pairs of fibrils can entwine to form fibres. Such self-assembling peptides are important biomaterials and may be useful for the development of novel biomaterials for tissue engineering scaffolds and dental enamel remineralisation.
