What is LL37?

LL37 (Cathelicidin) is a naturally occurring human antimicrobial peptide with potent immunomodulatory, anti-inflammatory, and tissue regenerative properties. It is researched for its potential to support immune defence, wound healing, and overall tissue health.

Key Features

  • Broad-spectrum antimicrobial activity
  • Dual immune modulation and tissue repair roles
  • Well-characterised cathelicidin research profile
  • High purity ≥98% verified by RP-HPLC

Mechanism of Action

LL37 disrupts bacterial membranes through electrostatic interactions and pore formation, while also modulating immune responses via TLR4 and FPRL1 receptor pathways. Research indicates roles in neutrophil recruitment, angiogenesis promotion, and epithelial cell migration for wound repair.

Research Applications

  • Antimicrobial and immune defence research
  • Wound healing and tissue repair studies
  • Anti-inflammatory pathway investigation
  • Skin barrier function and dermal health research
  • Respiratory mucosal defence studies

Reconstitution Guide
