Immune & InflammatorySynthetic research compound

LL-37

$59.99

5 mg

LL-37 is the active 37-residue peptide released from human cathelicidin (hCAP18), and the only cathelicidin-derived antimicrobial peptide identified in humans.

It is amphipathic and cationic, allowing it to interact with negatively charged microbial membranes, and it is studied both as an antimicrobial agent in vitro and as a signaling molecule involved in innate immune responses.

What you should know

More detail on LL-37.

Analytical values reflect per-lot documentation and appear once a batch is released.

Compound

LL-37 has a dual research profile. As an antimicrobial, it disrupts bacterial membranes in a concentration-dependent manner, and it is a standard reference peptide in minimum-inhibitory-concentration and membrane-permeabilization assays. As an immune modulator, published work describes interactions with host cell receptors, influence on chemotaxis, and binding to nucleic acids that alters innate sensing. Laboratory applications span microbiology, biophysics, and immunology. Activity is strongly salt- and serum-dependent, so assay conditions must be reported carefully.
