Product Introduction

LL‑37, also known as human cathelicidin peptide, is a synthetic 37‑amino‑acid host‑defense antimicrobial peptide derived from hCAP‑18 precursor protein. It is supplied as high‑purity white to off‑white lyophilized powder for laboratory research. This research material is widely adopted for in‑vitro experiments focusing on innate immunity, antimicrobial mechanism, inflammatory response and cell‑related biological pathway exploration. Each production batch undergoes HPLC and MS quality verification, and COA documents can be provided upon request for lab evaluation.

Mechanism of Action

LL‑37 interacts with negatively charged microbial membrane structures under experimental conditions. It participates in multiple immune‑related signal transduction pathways in pre‑clinical test models. Laboratory studies focus on observing its biological influences on pathogen membrane activity, immune cell chemotaxis and inflammatory‑related cell populations within in‑vitro assay systems.
