LL-37 is the only human member of the cathelicidin family of antimicrobial peptides. It is a naturally occurring host-defence peptide and is widely studied in the immunology and microbiology research literature.

Where LL-37 sits in the research literature

The evidence base includes extensive cell and animal studies of antimicrobial activity and immune signalling. Laboratory findings should not be extrapolated to people.

Reported areas of preclinical interest

  • Antimicrobial activity: studied for direct effects on microbial membranes in laboratory assays.
  • Immunomodulation: examined for effects on host-defence and inflammatory signalling.

Why the “research use only” label matters

LL-37 is supplied as a research material and is intended strictly for laboratory and scientific research, not for human or veterinary consumption.

Handling and storage

Store lyophilised peptide cool, dry and away from light, and refrigerate reconstituted solution, using it within the indicated stability window. Follow the documentation supplied with each batch.

Frequently asked questions

What is LL-37 studied for?
