LL-37 5mg – Lyophilized Antimicrobial Research Peptide

LL-37 is a cationic antimicrobial peptide belonging to the cathelicidin family, supplied here in a sterile lyophilized 5mg vial for advanced research applications. It has been studied extensively for its broad-spectrum antimicrobial activity, innate immune modulation, and role in tissue regeneration pathways.

In laboratory research, LL-37 has been observed to disrupt microbial membranes due to its amphipathic nature, making it a valuable model for host–pathogen interaction studies. Beyond its antimicrobial action, LL-37 is also of interest for its immunomodulatory functions, including the regulation of cytokine expression, chemotactic signaling, and inflammation control. Additionally, it has been examined in wound-healing research due to its influence on angiogenesis and extracellular matrix remodeling.

This dual functionality—direct antimicrobial disruption and indirect immune regulation—makes LL-37 an essential peptide for multi-pathway biological research. The lyophilized format ensures long-term stability until reconstitution, and every vial is manufactured under sterile conditions with full third-party verification to confirm peptide identity, molecular weight, and ≥98% purity.
