LL-37 is a linear, amphipathic, alpha-helical peptide and the sole representative of the cathelicidin family of antimicrobial peptides (AMPs) found in humans. When you buy LL-37 peptide, you receive a compound that functions in laboratory models as a primary component of cellular innate immunity. Its mechanism relies heavily on its net positive charge (+6) and hydrophobic regions, which allow it to bind selectively to negatively charged lipids on bacterial cell membranes.
Upon binding, LL-37 inserts itself into the lipid bilayer, causing membrane disruption, pore formation, and rapid cellular lysis. Beyond its direct antimicrobial profile, LL-37 acts as a potent immunomodulator by crossing cell membranes to interact with internal receptors like FPR2. This signaling upregulates angiogenesis, accelerates tissue re-epithelialization, and coordinates cellular migration patterns during wound healing assays.
