Documentation
Every LL-37 vial ships with a lot file.
COA, HPLC chromatogram, MS identity confirmation, water content and storage notes. We do not invoice without context — buyer track and destination are confirmed first.
MS identity
Mass spectrometry identity confirmation against the LL-37 reference mass profile.
Lot traceability
Lot code is printed on the vial label and reflected in the document pack. Reorders cite the prior lot for continuity.
FAQ
Common LL-37 questions from B2B buyers.
What is LL-37 used for in research contexts?
LL-37 is a 37-amino-acid cathelicidin peptide and the only cathelicidin found in humans. It is studied for its role in innate immunity, antimicrobial activity, and modulation of inflammatory responses. Research labs and 503A compounding pharmacies source lyophilized LL-37 for protocol development and laboratory study.
What is your minimum order quantity?
Sample lots from 50 vials; production lots start at 200 vials with tier pricing. Repeat OEM orders are scheduled in 1,000-vial batches with locked packaging.
What documentation do you ship with each lot?
Every batch ships with a Certificate of Analysis showing HPLC purity, MS identity, water content, and lot traceability. HPLC and MS chromatograms are available on request as part of the document pack.
Can you do private-label LL-37 packaging?
Yes. Neutral or branded vial labels, carton design, document packs, and lot-code handling are available for repeat OEM supply. See the OEM service path for the full process.
How do you ship internationally?
Lyophilized LL-37 ships at controlled temperature with documentation. Destination country and buyer track are confirmed before shipment. We work with B2B and research buyers, not consumers.
