Description
What is LL-37?
LL-37 is the only cathelicidin-family antimicrobial peptide humans produce — a 37-residue helix (starting with two leucines, hence the name) released by immune and epithelial cells as a first line of innate defence. It disrupts bacterial membranes directly, neutralizes endotoxin, and doubles as an immune signalling molecule that recruits and modulates host cells.
Interest has intensified with antibiotic resistance: LL-37 features in biofilm studies, wound-repair models, autoimmunity work (psoriasis, lupus), and next-generation antimicrobial design. It is one of the most complex — and most cited — molecules in the innate-immunity literature.

Why buy LL-37 as a 10-pack
Single-vial retail pricing punishes people who actually use volume. Our 10-pack format works out to $66.50 per vial — up to 30% below typical single-vial retail in Canada — and because every vial ships from one production lot, a single certificate of analysis covers your entire supply. One order, one batch, zero between-vial variance.
Quality & testing
Every lot is independently tested for identity (mass spectrometry) and purity (HPLC) before release. Packs ship cold-packed with tracking from our Canadian facility, and each order automatically includes one free vial of bacteriostatic water.
