LL37

LL-37 – 5mg Research Peptide

Human Cathelicidin Antimicrobial Peptide

For In Vitro Research Use Only – Not for Human or Animal Use

Product Overview

LL-37 is a synthetic form of the human cathelicidin antimicrobial peptide derived from the precursor protein hCAP-18. It is the only known cathelicidin identified in humans and is extensively studied in laboratory research for its involvement in innate immune defense, microbial membrane interactions, and immune-related cellular signaling pathways.

In vitro research models commonly utilize LL-37 to examine host-defense peptide mechanisms, inflammatory modulation, epithelial repair processes, and antimicrobial activity across a broad range of microorganisms. Its amphipathic and cationic structure makes it a valuable compound for studying peptide-membrane interactions and immune system signaling dynamics.

PureLabs LL-37 is supplied as a high-purity lyophilized peptide for controlled experimental applications.
