What is LL-37?

LL-37 (Cathelicidin antimicrobial peptide (hCAP-18 C-terminal)) is a 37-amino acid cationic alpha-helical peptide. Human cathelicidin C-terminal domain adopting alpha-helical conformation in membranes. Disrupts bacterial membranes via electrostatic interaction with anionic phospholipids, modulates TLR2/4 signalling to prevent hyperinflammation, promotes wound healing via keratinocyte migration, and exerts antiviral and antifungal activity.

Research Applications

Antimicrobial Mechanism

Membrane disruption against Gram+/Gram- bacteria, biofilm inhibition

TLR Signalling Modulation

TLR2/4 immune balance — pathogen clearance without excess inflammation

Wound Healing

Keratinocyte migration, re-epithelialisation, angiogenesis promotion

Antiviral Activity

Enveloped virus membrane disruption and innate antiviral response

Host Defence Biology

Innate immunity, antimicrobial peptide structure-activity research

Frequently Asked Questions

How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves — do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8°C.
How should this peptide be stored?
Store lyophilized peptide vials at −20°C for long-term storage. Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this QSC compound and how is it verified?
All QSC compounds are tested to ≥99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.

Frequently asked questions

How does my subscription work?

A seemingly elegant design can quickly begin to bloat with unexpected content or break under the weight of actual activity. Fake data can ensure a nice looking layout but it doesn’t reflect what a living, breathing application must endure. Real data does.

How do I edit what's in my plan?

Websites in professional use templating systems. Commercial publishing platforms and content management systems ensure that you can show different text, different data using the same template. When it’s about controlling hundreds of articles, product pages for web shops.

Can I change my next delivery date?
