LL-37 research peptide — only known human cathelicidin antimicrobial peptide. Used in immune and antimicrobial research.

LL-37 is the C-terminal fragment of human cathelicidin antimicrobial protein hCAP18 — the only cathelicidin found in humans. It is one of the most studied antimicrobial research peptides.
LL-37 disrupts microbial membranes through electrostatic interactions and induces immune signaling cascades. Research has explored its broad-spectrum antimicrobial activity and immunomodulatory roles.
Used in: antimicrobial research, immune research models, wound research, biofilm research, comparative AMP studies.
