• 
  
• Biological Functions:                                                
• 
  
• 1、Antimicrobial Activity:
• Primarily through the "carpet-like" model or "toroidal pore" formation in microbial membranes, causing membrane disruption and cell lysis. Its cationic nature interacts with negatively charged microbial membranes, while hydrophobic residues allow insertion into lipid bilayers.
• 2、 Immune Modulation (Dual Role): Pro-inflammatory Effects / Anti-inflammatory Effects
• • 3、 Other Key Functions:
    Wound Healing: Promotes re-epithelialization, angiogenesis, and tissue repair
    • Antitumor Activity: Inhibits cancer cell proliferation and migration, induces apoptosis
    • DNA/RNA Interactions: Forms complexes with nucleic acids, stimulating plasmacytoid dendritic cells to produce type I interferons
    • Anti-biofilm: Disrupts established biofilms and prevents new formation

• 

  Lyophilization Technology Advantages:                 
• 
  

  Our LL37 undergoes state-of-the-art freeze-drying process that delivers unmatched benefits:

  1、Maximum Activity Retention: Preserves LL37's native structure and biological activity by avoiding thermal degradation

  2、 Exceptional Stability: Extends shelf life to 24 months when stored properly (vs. 3-6 months for liquid forms)

  • 3、Enhanced Purity: Removes residual solvents and moisture completely, minimizing degradation factors
  • 4、Easy Reconstitution: Dissolves rapidly in sterile water or saline with no clumping
  • 5、Reduced Contamination Risk: Aseptic manufacturing process ensures product safety

  
  
  
  

• Clinical Significance:                                                
• • 1、First-line defense against infections (innate immunity)
  • 2、Protection of mucosal surfaces and skin
  • 3、Wound repair and tissue regeneration
  • 4、Potential therapeutic agent for antibiotic-resistant infectionsPMC
