Klvff fluorescence
WebBy combining KLVFF peptide and self-assembly chaperone we fabricate a new system to achieve the synchronization between Aβ fibril disaggregation and reducing toxicity of Aβ fragments (monomers or oligomers) that consequently formed. When the KLVFF peptides disaggregate fibrils into fragments, the hydrophobic Celebrating the ChemComm … WebMay 8, 2024 · To mimic self-assembling β-sheet structured fibrous networks of the natural HD6, KLVFF, a β-sheet structured sequence, was introduced into HDMP. In addition, the control peptide with weak β-sheet structured sequence (C-HDMP), BP-KAAGG-RLYLRIGRR (fig. S2C), and C-HDMP NPs were prepared (fig. S3).
