LL-37 scrambled peptide is a peptide consisting of 37 amino acids. It has the same amino acids as the antimicrobial peptide LL-37, but the sequence is different. LL-37 scrambled peptide is an artificially designed antibacterial peptide LL-37 scrambled peptide, which can be used as a negative control for LL-37 peptide research. The study of such peptide will help to better understand the antibacterial mechanism of LL-37.
