Abstract
Synthetic cationic peptides with amphiphilic α-helical structure were found to have DNA binding ability to stabilize double and triple stranded DNA. The stabilization effect was significant for cationic α-helical peptides indicating the importance of an electrostatic interaction of a positive charge of peptides and a negative charge of DNAs.
