Here, polybasic helical peptides, such as peptide p5, bind human amyloid extracts and synthetic amyloid fibrils. When radio labeled, peptide p5 has been shown to specifically bind amyloid in vivo thereby allowing imaging of the disease. Structural requirements for heparin and amyloid binding have been studied using analogues of p5 that modify helicity and chirality.
