Buy LL-37 — Cathelicidin-Derived Antimicrobial Research Peptide
Researchers looking to buy LL-37 for laboratory study will find this synthetic 37-amino-acid peptide is the only known cathelicidin-derived peptide expressed in humans and one of the most extensively researched host-defense peptides in modern immunology and microbiology literature. LL-37 is derived from the C-terminal end of the human cathelicidin antimicrobial protein (hCAP-18), and is studied across antimicrobial activity, innate immunity, chemotaxis, angiogenesis, and wound repair research models.
Mechanism of Action
LL-37 has been investigated in published research for activity across several biological pathways, including:
- Antimicrobial activity — disruption of bacterial, viral, and fungal membranes in preclinical models
- Immune modulation — interaction with innate immune signaling and cytokine pathways
- Chemotaxis — recruitment of immune cells including neutrophils, monocytes, and T-cells in research models
- Angiogenesis — formation of new blood vessels and capillary networks
- Wound and tissue repair — research on keratinocyte migration and epithelial repair processes
- Biofilm research — investigations into bacterial biofilm formation and disruption
Because of its dual role as both a direct antimicrobial agent and an immune modulator in preclinical research, LL-37 has become a foundational reference compound in host-defense peptide literature.
Research Applications
LL-37 is widely used in research contexts including:
- Antimicrobial and antibacterial pathway studies
- Innate immunity and host-defense peptide research
- Wound healing and epithelial repair investigations
- Biofilm and microbial resistance research models
- Inflammatory pathway and cytokine signaling studies
- Comparative analysis against other cathelicidin and defensin-class peptides
Product Specifications

Reconstitution & Storage
Lyophilized LL-37 should be stored at -20°C for long-term stability and protected from light. Once reconstituted with bacteriostatic water, the solution should be refrigerated at 2–8°C and used within the timeframe indicated on the product COA. Avoid repeated freeze-thaw cycles, as they can degrade peptide integrity.
Shipping & Handling
All orders are shipped with temperature-controlled packaging to preserve peptide integrity. Domestic orders typically arrive within 2–4 business days. Tracking is provided on every order.

Storage & Handling
Proper storage and handling are essential to maintaining peptide stability and ensuring the integrity of your research material.
Storage Recommendations
Lyophilized peptides should be stored at -20°C for long-term preservation. For short-term storage of up to 30 days, refrigeration between 2-8°C is acceptable. Reconstituted peptides should always be refrigerated and used within 30 days.
Avoid the following:
Direct sunlight or UV exposure Repeated freeze-thaw cycles Temperature fluctuations Storage at room temperature beyond brief handling periods
Reconstitution Best Practices
Allow vials to reach room temperature before opening to prevent condensation. Use bacteriostatic water as the diluent for most peptides, injecting slowly along the side of the vial. Gently swirl to dissolve — do not shake. Allow the solution to fully dissolve before drawing for research use.
Shelf Life
Lyophilized peptides maintain potency for up to 24 months when stored properly at -20°C. Reconstituted solutions should be used within 30 days for optimal research results.
Research Use Only
All products supplied by Kinetic Compounds are intended strictly for in-vitro laboratory research and development purposes.
