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 Vesta compound and how is it verified?
All Vesta 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.
