LL-37 5 MG

Dragon Pharma LL-37 5 mg – Natural Human Antimicrobial Peptide for Immune Research

Dragon Pharma LL-37 5 mg is a natural human antimicrobial peptide derived from the cathelicidin protein. Consisting of 37 amino acids, LL-37 serves as a critical component of the innate immune system, acting as a first-line defense against microbial pathogens and playing important roles in wound healing and inflammation regulation.

Each vial contains 5 mg of lyophilized LL-37 in a 2 mL format, requiring reconstitution with bacteriostatic water before use. This peptide has been extensively studied for its broad-spectrum antimicrobial activity against bacteria, viruses, and fungi, as well as its immunomodulatory properties and ability to promote wound healing.

What Makes LL-37 Valuable in Research?

LL-37 is one of the most well-characterized antimicrobial peptides in the human immune system. It demonstrates a unique dual function: direct antimicrobial activity through membrane disruption and immunomodulatory effects that influence host immune responses. Its ability to neutralize endotoxins, modulate inflammatory cytokine production, and promote epithelial cell migration makes it a valuable tool for studying innate immunity and tissue repair.

Researchers value LL-37 for its broad-spectrum activity and its role in connecting innate and adaptive immune responses. Its involvement in wound healing, angiogenesis, and chemotaxis makes it relevant to studies ranging from infectious disease to tissue regeneration. For investigators exploring other immune-modulating compounds, Thymosin Alpha-1 offers complementary research avenues in immune system regulation.

Current scientific literature on LL-37 can be accessed through the PubMed database, where researchers can review peer-reviewed studies on its biological activity and experimental applications.

Dosage & Usage Guidelines

Reconstitution Protocol

• ✔ Use sterile bacteriostatic water for injection
• ✔ Add appropriate volume to achieve desired concentration
• ✔ Swirl gently to dissolve – do not shake vigorously
• ✔ Store reconstituted solution at 2–8°C

Reconstitute the lyophilized powder using bacteriostatic water to a concentration suitable for your research protocol. The 5 mg format allows for precise dosing across a range of experimental models. Always use aseptic technique during preparation to maintain peptide integrity.

Typical Research Parameters

In research settings, LL-37 is typically administered via subcutaneous or topical application. Dosing schedules and concentrations vary widely depending on the experimental design, animal model, and specific research objectives.

• ✔ Commonly used in antimicrobial and immune response studies
• ✔ Often combined with microbiological and immunological analysis
• ✔ Used to investigate wound healing and tissue repair mechanisms
• ✔ Research models include infection, inflammation, and tissue injury paradigms

Factors to Consider in Research Protocols

• Natural human peptide with broad-spectrum activity
• Reconstitution stability is limited; prepare fresh solutions for each use
• Individual variation in response may be observed across subjects
• Storage conditions significantly impact peptide stability

Storage

Store the lyophilized powder at controlled room temperature (15–25°C) in a dry, dark place, away from direct light and moisture. The unopened vial should be kept in its original packaging to maintain stability.

After reconstitution, store the solution at 2–8°C and use within 14 days. Do not freeze. Discard any unused portion after the recommended storage period. Before use, inspect the solution and avoid use if it appears cloudy, discolored, or contains particulate matter, or if the vial or seal is compromised.

Keep out of reach of children. Follow proper handling and sterile injection practices during research use.

Proper storage conditions help maintain product stability and consistent performance across the product's shelf life.
