Buy LL-37 5mg (CAP-18) for Antimicrobial & Tissue Regeneration Research


What is LL-37 (CAP-18)?

LL-37 (also known as CAP-18) is a cationic antimicrobial peptide derived from the human cathelicidin family, extensively studied for its role in innate immune defense, tissue repair, and inflammation modulation.
This peptide is the only known human cathelicidin and is produced by epithelial cells and immune cells such as neutrophils.

Researchers use LL-37 5mg to explore infection control mechanisms, epithelial regeneration, and wound healing responses in both in vitro and in vivo models.


How Does LL-37 (CAP-18) Work?

LL-37 exerts multiple biological actions across diverse cell types. Research indicates it:

  • Disrupts microbial membranes, exhibiting broad-spectrum antibacterial, antifungal, and antiviral activity.

  • Modulates immune cell signaling, influencing cytokine production and inflammation resolution.

  • Stimulates angiogenesis and collagen synthesis, promoting tissue repair and regeneration.

  • Supports epithelial defense in the respiratory, gastrointestinal, and dermal systems.

Because of these multifaceted properties, LL-37 is a valuable peptide in infection, immunity, and wound healing research.


Key Benefits of LL-37 5mg (CAP-18) for Research

  • Potent antimicrobial properties against bacteria, fungi, and viruses

  • Enhances tissue regeneration and collagen remodeling

  • Regulates immune response and inflammation

  • Supports skin and mucosal defense studies

  • Explored for chronic wound and infection model research

This peptide is intended strictly for laboratory research and not for human or clinical use.
