LL‑37 is the only human cathelicidin antimicrobial peptide, derived from the hCAP18 protein. It is a 37‑amino acid cationic, amphipathic α‑helical peptide with broad immunomodulatory and host defense functions.
It exhibits potent antimicrobial activity against Gram‑positive and Gram‑negative bacteria, fungi, and enveloped viruses. Beyond direct microbial killing, LL‑37 regulates inflammation, promotes wound healing, modulates immune cell recruitment, and supports tissue repair. It is widely studied in immunology, dermatology, infection research, and mucosal defense.
Production：
Manufactured via solid-phase peptide synthesis (SPPS), followed by purification and lyophilization to obtain the final product.
