LL-37 5mg Peptide

LL-37 works through charge and shape rather than through a receptor: its cationic amphipathic helix inserts into anionic bacterial membranes and disrupts them, a mechanism that makes resistance development slow compared with conventional antibiotics. Alongside that direct activity it acts as a signalling molecule, driving chemotaxis, angiogenesis and re-epithelialisation, and it is this dual role that makes it interesting in wound-healing models. It is also implicated in the pathology of psoriasis and rosacea, so the literature cuts both ways. This 5mg vial is sized for the low working concentrations typical of antimicrobial assays.
