LL-37

Also known as: Cathelicidin Antimicrobial Peptide

Immune / AntimicrobialGrey areaHalf-life: 1h

Overview

LL-37 is an endogenous human antimicrobial peptide derived from cathelicidin. It is studied for broad antimicrobial, immune-modulating, wound-healing, and inflammatory signalling properties, but it is not an approved general-use medicine.

How it works

Disrupts microbial membranes and can neutralise endotoxins. Also modulates innate immune signalling, chemotaxis, angiogenesis, epithelial repair, and inflammatory cytokine responses. Its effects are context-dependent and may be pro- or anti-inflammatory depending on tissue environment.

Primary uses

  • Antimicrobial research
  • Innate immunity
  • Wound healing research
  • Inflammation signalling
  • Biofilm research

Storage and preparation

Store lyophilised material at -20°C away from light and moisture. After reconstitution, refrigerate and use within validated stability guidance. Avoid repeated freeze-thaw cycles.

Reconstitute with sterile water, bacteriostatic water, or buffer depending on research application. Some antimicrobial peptides may adsorb to plastics, so follow supplier handling notes.
