    What Is LL-37 5mg?

    LL-37 5mg Vial Overview

    LL-37 is a 37-amino acid antimicrobial peptide and the only human cathelicidin. It plays a crucial role in innate immunity by directly killing bacteria, viruses, and fungi through membrane disruption. Beyond antimicrobial activity, LL-37 modulates immune responses, promotes wound healing through angiogenesis, and influences tissue remodeling.

    LL-37 5mg Compared With Other Formats

    Details that distinguish this 5 mg format include:

    • Only human cathelicidin antimicrobial peptide
    • Broad-spectrum activity against bacteria, viruses, and fungi
    • Immune modulation beyond direct antimicrobial action

    How Does LL-37 Work?

    LL-37 Mechanism of Action

    LL-37 kills pathogens by disrupting microbial membranes through electrostatic interaction with negatively charged lipid bilayers. Beyond antimicrobial activity, it activates formyl peptide receptors (FPR2), recruits immune cells, promotes angiogenesis for wound healing, and disrupts bacterial biofilms. It bridges innate and adaptive immunity.

    What Are the Potential Benefits of LL-37?

    2 mL
    Final Concentration
    2.5 mg/mL

    LL-37 5mg Mixing Instructions

    1. 1Remove the vial from storage and allow it to reach room temperature (10–15 minutes).
    2. 2Wash hands thoroughly and prepare a clean workspace with all supplies.
    3. 3Using a sterile syringe, draw the appropriate volume of bacteriostatic water.
    4. 4Clean the rubber stopper of the vial with an alcohol prep pad.
    5. 5Insert the needle at a slight angle and slowly inject the diluent down the inner wall of the vial.
    6. 6Gently swirl or roll the vial until fully dissolved; the solution should appear clear and colorless.
    7. 7Label the vial with reconstitution date and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light. Use within 2–4 weeks.

    LL-37 5mg FAQs

    Can LL-37 replace antibiotics?

    No. LL-37 is a research compound and not a substitute for prescribed antibiotics. It is studied for its complementary immune-enhancing properties.

    Why are doses so low compared to other peptides?

    LL-37 is highly potent at microgram levels. Its membrane-active mechanism means excessive doses could cause tissue irritation.
