About this product

Product information from the supplier.

LL-37 is a potent 37-amino-acid antimicrobial and host defense peptide, serving as the sole human member of the cathelicidin family. This critical biological molecule acts as a primary shield in the innate immune system, providing a rapid response to protect the organism from a wide array of pathogens.

Beyond its direct antimicrobial capabilities, LL-37 plays a sophisticated role in regulating inflammation and modulating the immune response. By balancing pathogen defense with the regulation of the body's inflammatory pathways, it ensures a coordinated biological response essential for maintaining systemic homeostasis.

Frequently Asked Questions

Q: What is the primary application of LL-37 in biopharmaceutical manufacturing?

LL-37 is primarily used in the development of antimicrobial drugs, vaccine adjuvants, and research concerning the regulation of the innate immune response and inflammatory diseases.

Q: How does LL-37 differ from other antimicrobial peptides?

Unlike synthetic antimicrobial peptides, LL-37 is the only human member of the cathelicidin family, offering unique bio-compatibility and a dual role in both killing pathogens and modulating inflammation.

Q: What storage conditions are recommended for LL-37 peptides?

To maintain structural integrity and biological activity, LL-37 should be stored in a lyophilized state at -20°C or -80°C, protected from light and moisture.

Q: Can LL-37 be used for genetic engineering in vaccines?

Yes, its ability to interact with cell membranes and modulate immune responses makes it a highly valuable component in the design of next-generation genetically engineered vaccines.

Q: How is the purity of LL-37 verified during production?

We utilize High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) to ensure the peptide sequence is accurate and the purity levels meet pharmaceutical standards.

Q: What is the role of LL-37 in host defense?

LL-37 acts by disrupting the cell membranes of invading bacteria and fungi, while simultaneously signaling other immune cells to the site of infection to coordinate a full host defense.
