LL-37 is the only human cathelicidin antimicrobial peptide, a key effector of the innate immune system.
What it is
LL-37 is studied for directly disrupting microbial membranes and for immunomodulatory signaling — influencing chemotaxis, wound-healing pathways, and inflammation. It is a central reference peptide in antimicrobial-peptide research.
How it’s studied
Research interest covers antimicrobial activity, innate-immune signaling, and tissue-repair models.
Research focus areas
- Membrane-disrupting antimicrobial activity
- Innate-immune and chemotaxis signaling
- Wound-healing pathway research
- Host-defense peptide biology
Handling & documentation
In the laboratory this material is typically supplied as a lyophilized (freeze-dried) powder and reconstituted with bacteriostatic or sterile water for in-vitro work. As with any research compound, the quality signal that matters most is a lot-specific Certificate of Analysis (COA) from an independent lab, confirming identity by mass spectrometry and purity by HPLC. Store per the supplier’s guidance and verify the COA before use.
