Buy LL-37 (CAP-18) 5mg — 10-Vial Kits
Natural immune-defense peptide
LL-37 is a peptide the human body makes naturally, 37 amino acids long. It is the active part of a germ-fighting protein called cathelicidin, which the body's immune cells produce. The research version is made in the lab.
How it is studied
Researchers describe it as a germ-fighting and immune-signaling peptide: it can break apart the outer coats of microbes and can interact with immune cells that guard the body. Scientists study these germ-fighting and signaling actions in the lab.
Research context
A reference compound in early germ-defense, immune-system and wound-biology research, where investigators study how it acts on microbes and immune cells in lab studies.
Good to know
A natural immune peptide studied mainly in cell and animal research. Research use only.
