LL-37 5mg (CAS 154947-66-7) – Antimicrobial Peptide API

LL-37 5mg (CAS 154947-66-7) is a high-purity antimicrobial peptide API, featuring ≥98% purity (HPLC-verified) and a defined 37-amino-acid cationic structure (molecular weight: ~4493 Da). As a key human cathelicidin-derived peptide, it exerts broad-spectrum antimicrobial activity against bacteria, fungi, and enveloped viruses, while also regulating immune responses to reduce inflammatory damage.

This white to off-white lyophilized powder dissolves easily in water or normal saline, with stable biological activity under -20℃ storage. It is widely used in preclinical research: it supports the construction of microbial infection models, explores antimicrobial-immune synergy mechanisms, and aids in developing novel anti-infective research tools. For pharmaceutical R&D teams, its dual antimicrobial-immunomodulatory properties and consistent quality make it a reliable raw material for anti-infective and immune-related research.
