About this peptide

LL-37 (cathelicidin LL-37) is a 37-amino acid synthetic peptide corresponding to the human cathelicidin antimicrobial peptide. Research applications span antimicrobial activity studies, wound healing models, and innate immune signaling. Half-life is short. Supplied as lyophilized powder; light-sensitive — store away from direct light. Reconstitute at 1–2 mg/mL in sterile water; refrigerate. HPLC purity ≥ 99.0% with in-house HPLC/LC-MS verification; independent third-party re-verification is available on request.

Questions about LL-37 5mg — 10-Vial Pack

How is LL-37 5mg — 10-Vial Pack reconstituted?

+

LL-37 5mg — 10-Vial Pack is supplied as lyophilized powder under nitrogen. Typical reconstitution is in sterile or bacteriostatic water; the exact concentration depends on your protocol. Our free reconstitution calculator computes mL per dose and insulin-syringe units from any combination of vial size, water volume, and target dose.

What is the HPLC purity of this batch?

+

Batch LL-2607 of LL-37 5mg — 10-Vial Pack is verified in-house at 99.8% HPLC main-peak purity, with molecular weight confirmed by LC-MS and endotoxin screened by LAL assay. That in-house COA — chromatogram, mass spec trace, and purity call — is bundled with your order as a downloadable PDF. Independent third-party re-verification can be arranged for a specific batch on request; it isn't run by default.

How does QSC ship internationally?

+

One fully automated, self-serve method, 10% off: "Pay with crypto or card" at checkout takes a direct crypto payment from your own wallet (Bitcoin, Ethereum, USDT, USDC and more) or a normal card payment via our card-to-crypto processing partner — no crypto wallet needed for cards. Wire transfer, PayPal, and Revolut can be arranged by email before you order, at the regular price without the 10% discount. ACH is temporarily paused. Full payment-method details are on the shipping & payment page.

Should LL-37 be paired with other peptides in research protocols?

+

LL-37 can be studied alone or in combination with other tissue repair peptides depending on your research design. Common pairings appear in published literature; the QSC catalog includes pre-bundled stacks for the most-cited combinations.

Is LL-37 administered locally or systemically in published research?

+

Most published rodent studies in tendon and ligament repair use peri-lesion subcutaneous or intramuscular administration to concentrate the molecule at the repair site. Systemic (sub-Q at a distant site) administration is also reported, particularly for studies probing systemic immune or gut effects. Choice of route depends on the experimental question.
