H2 Research-Grade Human Cathelicidin Peptide for Innate Immunity and Host Defense Research

LL-37 is the only naturally occurring cathelicidin antimicrobial peptide identified in humans. Derived from the precursor protein hCAP18, this 37-amino-acid peptide plays a central role in innate immune defense and has become one of the most extensively studied host-defense peptides in modern biomedical research.

Unlike many research peptides that primarily target endocrine or growth-related pathways, LL-37 is investigated for its involvement in immune signaling, microbial interactions, epithelial barrier function, biofilm biology, and tissue repair mechanisms. Because of its broad biological activity, LL-37 continues to be an important research tool across immunology, microbiology, dermatology, and molecular biology laboratories.

Our research-grade LL-37 is manufactured under strict quality standards and supplied exclusively for laboratory, scientific, and educational research.

What Is LL-37?

LL-37 is a positively charged, amphipathic peptide consisting of 37 amino acids, with its name originating from its sequence beginning with two leucine (L) residues. It is produced through enzymatic cleavage of the precursor protein hCAP18 and is expressed by neutrophils, macrophages, and epithelial cells throughout the skin, respiratory tract, gastrointestinal tract, and other tissues.

Researchers study LL-37 because it serves multiple biological functions beyond direct antimicrobial activity. Experimental evidence suggests it participates in immune cell recruitment, inflammatory regulation, epithelial repair, and communication between innate and adaptive immune systems. These diverse activities have made LL-37 a cornerstone molecule in host-defense peptide research.

Why Researchers Study LL-37

Innate Immune System Research

LL-37 is widely investigated as a key component of the body’s first-line immune defense. Researchers examine how it contributes to early immune responses against microbial challenges.

Host Defense Peptide Biology

As the only human cathelicidin, LL-37 provides an important model for understanding how host-defense peptides interact with pathogens while also regulating immune communication.

Immune Signaling

Beyond antimicrobial activity, LL-37 is studied for its ability to influence chemotaxis, cytokine signaling, and interactions between immune cells during inflammatory responses.

Biofilm Research

Laboratory studies have explored LL-37’s interactions with bacterial biofilms and microbial communities, making it relevant to research involving microbial persistence and host-pathogen interactions.

Epithelial and Tissue Biology

Researchers continue to investigate LL-37 in studies involving epithelial barrier function, re-epithelialization, extracellular matrix biology, and wound-related cellular communication.

LL-37 vs. BPC-157

Although LL-37 and BPC-157 are sometimes discussed together, they belong to different research categories.

Where To Buy LL-37 Peptide Germany
