LL-37 5mg

LL-37 is a high-purity synthetic form of the only known human cathelicidin antimicrobial peptide, recognized for its critical role in innate immunity, host defense, and tissue repair. Naturally produced by epithelial cells, neutrophils, and other immune cells, LL-37 serves as a multifunctional signaling molecule that helps coordinate immune responses, maintain barrier integrity, and support cellular healing processes.

Due to its broad biological activity, LL-37 has become an important research tool in immunology, microbiology, regenerative medicine, and cellular biology. Studies have demonstrated its ability to interact with a wide range of immune pathways involved in inflammation, pathogen recognition, and antimicrobial defense. Through these mechanisms, LL-37 has been extensively utilized in investigations examining host-pathogen interactions, innate immune regulation, and microbial defense strategies.

Beyond its antimicrobial properties, LL-37 has attracted significant attention for its potential role in tissue regeneration and wound-healing research. Evidence suggests that the peptide may influence cellular migration, angiogenesis, extracellular matrix remodeling, and the recruitment of immune cells to sites of injury. These effects have made it a valuable compound for studying the biological processes involved in tissue repair and recovery.

Researchers have also explored LL-37's involvement in inflammatory signaling, epithelial barrier function, and cellular communication networks that contribute to immune homeostasis. Its ability to bridge antimicrobial defense and regenerative pathways has positioned LL-37 as a unique molecule for investigating the intersection of immunity, tissue health, and cellular resilience.

As interest in host defense peptides continues to expand, LL-37 remains a cornerstone compound in research focused on innate immunity, wound healing, microbial interactions, and the mechanisms that support healthy tissue maintenance and repair.

Research Use Only
This product is intended solely for in vitro laboratory research purposes. It is not approved for human or animal use and must not be used in food, dietary supplements, pharmaceuticals, or cosmetic applications. All products arrive in lyophilized (freeze-dried) powder form.

Peptide Storage Guidelines

For optimal stability, lyophilized (freeze-dried) peptides should be stored in a cool, dry place when intended for short-term use. For long-term storage, refrigeration or freezing is recommended to help maintain peptide integrity and stability.

Amino Solutions are shelf-stable and should be stored at room temperature in a cool, dry location. Refrigeration is not recommended unless otherwise specified.

Bacteriostatic Water should also be stored in a cool, dry place at room temperature. Refrigeration may contribute to the formation of cloudiness or visible particulates, which can complicate peptide reconstitution procedures conducted for research purposes.

To preserve product quality, always keep protected from excessive heat, moisture, and direct sunlight.
