What Is LL-37 Peptide
LL-37 is a 37 amino acid cationic peptide derived from the C-terminal domain of the human cathelicidin protein hCAP-18. Researchers also refer to it as CAP-18. You can read a general scientific overview of cathelicidin peptides on Wikipedia.
Researchers use LL-37 in study models focused on antimicrobial defense, bacterial membrane disruption, immune cell activation, wound healing, anti-inflammatory signaling, and skin health research. Its position as the only human cathelicidin peptide makes it one of the most studied innate immune defense compounds in current research.
LL-37 Mechanism of Action and Research Background
LL-37 works by inserting into bacterial cell membranes and disrupting their integrity in research models. This leads to bacterial cell death through membrane depolarization and lysis. Researchers study this mechanism across gram-positive and gram-negative bacterial research models.
Beyond direct antimicrobial activity, LL-37 binds to receptors on immune cells. It activates dendritic cells, mast cells, and neutrophils in research models. It also modulates pro-inflammatory cytokine production. Researchers study it for both its direct antimicrobial effects and its broader immune modulation activity across multiple tissue systems.
LL-37 Research Administration Routes
Researchers study LL-37 through subcutaneous and topical administration routes in research settings. Subcutaneous injectable administration delivers the compound into systemic circulation for immune modulation and wound healing research models. Topical application is studied for skin health, antimicrobial, and wound healing research models.
Peptalynlabs.com supplies LL-37 at 99.9% purity in powder form. Researchers reconstitute it according to their protocol requirements.

What to Consider Before Starting a Peptide Reselling Business
Before sourcing LL-37 or any research compound for resale, new resellers should address the following:
- Confirm your jurisdiction's regulations on research peptide distribution
- Source only from suppliers who include a Certificate of Analysis on every order
- Build a compliant storefront with research-use-only disclaimers before listing products
- Identify your target buyer, whether individual researchers, immunology research groups, or laboratory procurement teams
- Start at low volume and scale as demand confirms itself
- Know customs requirements for peptide imports in your target markets
