LL-37 is a synthetic 37-amino-acid host defense peptide derived from the human cathelicidin precursor hCAP18. We supply it as a sterile-filtered lyophilized powder, typically ≥98% pure by HPLC, for research and formulation development.
Buyers source LL-37 for antimicrobial and immunomodulatory studies, often as a reference standard or as an active in topical and injectable prototypes. It ships from stock with full documentation and is available in gram to multi-gram quantities.
Formulators use LL-37 in antimicrobial gel and cream prototypes, wound-care dressings, and in vitro assays for biofilm disruption. It also appears in cell-culture media supplements and in studies on innate immune response. Because it is a cationic peptide, it interacts with anionic excipients and surfaces; formulation work should account for this compatibility.
