Research Overview

LL-37 is a 37-amino-acid human cathelicidin-derived antimicrobial peptide corresponding to the active C-terminal fragment of hCAP18. It is widely investigated in laboratory research involving innate immune signalling, antimicrobial peptide function, membrane-associated mechanisms, inflammatory pathway modulation, and host-defense peptide biology.

• Investigated in experimental models involving antimicrobial peptide activity and membrane interactions.
• Used in research exploring cathelicidin-related innate immune signalling pathways.
• Included in studies examining inflammatory response mechanisms and cellular signalling profiles.
• Applied in controlled laboratory investigations involving peptide stability, amphipathic peptide behaviour, and peptide-membrane interaction models.
• Studied in host-defense peptide research and epithelial barrier-related experimental systems.

Researchers frequently select LL-37 for controlled experimental models requiring a professionally handled, independently verified research product with transparent quality documentation.

Research Applications

• Antimicrobial peptide research

Quality & Testing

Every batch supplied by The Peptide Archive undergoes independent analytical verification through accredited third-party laboratories. Our quality-first approach prioritises transparency, consistency, and traceability, ensuring researchers receive products supported by objective analytical data rather than supplier documentation alone.

Where available, Certificates of Analysis and batch-specific testing information can be provided upon request. This commitment to independent verification forms part of our wider dedication to maintaining exceptionally high standards across our research catalogue.

Handling & Storage

• Store under suitable cold-chain conditions.
• Protect from direct light, moisture, and excessive heat.
• Reconstitute using appropriate sterile laboratory techniques where applicable.
• Avoid repeated freeze-thaw cycles where possible.
• Handle using suitable laboratory-grade equipment and procedures.
