LL-37 (Human Cathelicidin) – Synthetic 37-Amino Acid Peptide | Research Use Only

LL-37 is a synthetic 37-amino acid peptide corresponding to the active fragment of the human cathelicidin antimicrobial peptide precursor (hCAP18 / CAMP). It is classified as a cationic, amphipathic antimicrobial peptide (AMP) and represents the only cathelicidin identified in humans.

In research literature, LL-37 is studied as a host-defense peptide involved in innate immune signaling and peptide-mediated cellular response pathways.
