No. LL-37 is supplied exclusively as a research compound for in-vitro and non-human laboratory study. We do not provide health, dosing, or treatment guidance, and it must be handled by trained personnel following appropriate safety practices. All products are supplied strictly for laboratory and research use only and are not for human consumption.
Tested batches of LL-37 are independently analysed to a target purity of ≥99% by HPLC, MS. The exact figure for each batch is reported on its Certificate of Analysis.
LL-37 has a cas number of 154947-66-7, a molecular formula of c205h340n60o53 and a molecular weight of 4493.33 g/mol. Full technical details are listed in the technical data sheet on this page.
LL-37 should be stored as follows: Store lyophilized at -20°C, protected from light. Stable at ambient temperature for short-term shipping. Reconstitute with bacteriostatic or sterile water for laboratory use. Refrigerate (2–8°C) after reconstitution.
Yes. Tested batches of LL-37 are supplied with documentation of independent third-party purity and identity analysis, so researchers can verify exactly what they receive. The COA is available on this page or on request.
LL-37 is packaged discreetly and shipped worldwide with tracked delivery, typically dispatched within 24 hours of confirmed payment. Checkout is secure cryptocurrency only (BTC, ETH, LTC, USDT).
LL-37 is supplied as lyophilized white powder, sealed in a vial for laboratory research. Orders are packaged discreetly and shipped worldwide with tracking, typically dispatched within 24 hours of confirmed payment.
In the laboratory, LL-37 is reconstituted by dissolving the lyophilized powder in a suitable solvent such as bacteriostatic or sterile water. Reconstitute with bacteriostatic or sterile water for laboratory use. Refrigerate (2–8°C) after reconstitution. Our reconstitution calculator (under Research Tools) can help determine the concentration of the prepared solution. This is laboratory guidance only, not dosing advice.
Yes. LL-37 is also referred to as Cathelicidin antimicrobial peptide. These names all refer to the same research compound.
The amino-acid sequence of LL-37 is LLGDFFRKSKEKIGKEFKRIVQRIKDFLRNLVPRTES. The full technical data sheet, including molecular formula and weight, is shown on this product page.
Research compounds such as LL-37 can generally be purchased for laboratory research, but legal status varies by country and by specific compound. Buyers are responsible for knowing and complying with the laws and import regulations in their own jurisdiction. It is supplied for research use only and is not for human consumption.
Yes. We can accommodate larger research orders of LL-37. Contact our research-support team to discuss bulk quantities, current availability and pricing.

Research tool

Reconstitution calculator

Estimate the concentration of LL-37 once reconstituted, and the volume containing a target quantity. A laboratory measurement aid — research use only.

Reconstitution calculator

Solution concentration mg/mL ( mcg/mL)
Volume for target mL ( units)

The target volume exceeds the solvent added — increase the solvent volume or lower the target quantity.

For laboratory measurement and research use only. This tool reports the concentration of a reconstituted solution; it is not dosing guidance and the products are not for human or veterinary use. “Units” refer to graduations on a standard measuring syringe.
