LL-37 10mg

Research Overview

LL-37 is the 37-residue active peptide cleaved from human cathelicidin antimicrobial protein hCAP18, and it is the only cathelicidin identified in humans. Its cationic, amphipathic helical structure enables interaction with anionic microbial membranes, producing membrane destabilization that underlies its broad-spectrum antimicrobial activity in vitro. Beyond direct microbicidal action, LL-37 functions as an immunomodulatory signal: the literature describes chemotactic recruitment of immune cells, modulation of Toll-like receptor responses, neutralization of bacterial lipopolysaccharide, and influence on angiogenesis and wound repair. This dual identity — direct antimicrobial effector and host-defense signaling molecule — makes it a central subject in innate immunity research. Laboratory applications include minimum inhibitory concentration assays, membrane permeabilization studies, LPS neutralization experiments, chemotaxis assays, and biofilm research.

Why Researchers Choose This Product

As the sole human cathelicidin, LL-37 has no substitute in host-defense research — findings from it map directly onto human innate immune biology. Microbiology and immunology laboratories rely on it as both an antimicrobial reference peptide and an immunomodulatory probe.

Storage

Store lyophilized vials refrigerated at 2–8°C. Protect from heat and light. Reconstituted material should be kept refrigerated and handled under aseptic laboratory conditions. For laboratory research use only.

Frequently Asked Questions

What is LL-37 10mg studied for?

LL-37 is the only human cathelicidin-derived antimicrobial peptide, studied for innate immune signaling, membrane interaction, and immunomodulatory activity. Research applications span microbiology, host defense, and inflammatory pathway investigation in laboratory models.
