LL-37 10mg Research Peptide
LL-37 is the C-terminal active fragment of hCAP-18, the only cathelicidin produced by humans. It is constitutively expressed by neutrophils, epithelial cells and keratinocytes as a frontline component of the innate immune system.
Purity
99.2% HPLC-tested purity with COA support.
Size
10mg Lyophilized Powder.
Storage
-20°C (Freezer)
Research use
For laboratory research use only. Not for human or veterinary use.
Mechanism of action
LL-37 disrupts bacterial, fungal and enveloped-viral membranes via amphipathic helix insertion. Beyond direct microbicidal activity it modulates chemotaxis, angiogenesis and wound re-epithelialization, and shows activity against biofilm formation in research models.
Research applications
- Antimicrobial peptide research
- Biofilm and antibiotic-resistance studies
- Wound healing and re-epithelialization research
- Innate immunity research
- Antiviral research (enveloped viruses)
Frequently asked questions
Why is LL-37 of interest in antibiotic-resistance research?
LL-37 disrupts membranes by physical mechanism rather than a single molecular target. Bacterial resistance evolves slowly to that mechanism, making cathelicidins a leading template for novel antimicrobial development.
What forms does LL-37 come in?
Lyophilized synthetic 37-amino-acid peptide identical to native human LL-37 cleaved from hCAP-18.
What does the COA cover?
≥99.2% HPLC purity, mass-spec confirmation, endotoxin testing and lot-specific batch documentation.
