Research overview

About this compound

LL-37 is a 37-amino-acid peptide released from the C-terminus of the human cathelicidin protein hCAP18. It is cationic and forms an amphipathic alpha helix.

How it is used in research

It is used in microbiology and immunology research as a model antimicrobial peptide, including studies of membrane disruption in bacteria.

Analytical characterization

Synthetic peptides are usually characterized by reversed-phase high-performance liquid chromatography (HPLC), which reports purity as the share of the main peak, and by mass spectrometry, which confirms that the measured molecular mass matches the expected sequence. Results for a specific lot appear under Lab results once they have been posted.
