About LL-37
LL-37 is a 37-residue cationic peptide and the only human member of the cathelicidin family of antimicrobial peptides, named for the two leucine residues at its N-terminus. Beyond its host-defense origin, its amphipathic structure makes it a tool for investigating membrane interactions and innate-immune signaling.
Researchers examine LL-37 in studies of antimicrobial activity, immune modulation, wound-environment models, and angiogenesis. It is supplied as a lyophilized powder intended for reconstitution in suitable solvent under laboratory conditions, manufactured to ≥98% purity with a certificate of analysis available on request. This material is sold strictly for research use only.
