Cathelicidin peptide

LL-37 is the 37-amino-acid C-terminal peptide of human cathelicidin (hCAP-18), the only cathelicidin identified in humans. In published in vitro and preclinical literature it has been investigated for its role in innate-immune signalling and membrane-interaction models. Supplied lyophilized; purity and identity are reported per lot on that lot’s Certificate of Analysis. For laboratory and research use only — not for human or animal consumption. ROEHN makes no claims regarding its effects.
