LL-37 – 5mg

LL-37, also known as cathelicidin LL-37 or CAP-18 fragment, is a 37-amino-acid cationic amphipathic peptide derived from the C-terminal of human cathelicidin antimicrobial protein (hCAP18). It exhibits potent antimicrobial activity against bacteria, viruses, fungi, and parasites by disrupting microbial membranes through mechanisms such as pore formation and carpet-like disruption. Beyond direct antimicrobial effects, LL-37 modulates immune responses by promoting chemotaxis, cytokine production, mast cell activation, and dendritic cell function, while also supporting wound healing through enhanced re-epithelialization, granulation tissue formation, angiogenesis, and anti-biofilm activity in research models. Its dual role in innate immunity and tissue repair makes it a key tool for studying infection defense, chronic wound models, autoimmune conditions, and regenerative processes.
LL-37 is provided strictly for laboratory and research purposes only.
LL-37 is a synthetic antimicrobial and immunomodulatory peptide supplied in a 5mg vial as a lyophilized powder. It is provided exclusively for laboratory-based, in vitro research applications. LL-37 has been studied in experimental models for its potential role in antimicrobial defense, immune modulation, and wound healing pathways under controlled research conditions.
