LL-37 is/has been studied as the sole human member of the cathelicidin family, a crucial antimicrobial peptide (AMP) in innate immunity that fights bacteria, viruses, and fungi, while also modulating inflammation, wound healing, cell proliferation, and potentially influencing autoimmune diseases (like SLE) and cancer, acting as a bridge between innate and adaptive immunity by attracting immune cells and signaling. It disrupts bacterial membranes but also interacts with host cells and DNA, enhancing certain immune responses while suppressing others, making it a complex molecule with diverse roles in health and disease.

5 MG Lyophilized Powder in a Vial

Double tested at Janoshik labs (the gold standard of testing in Europe) and at Pure Analytical labs (ISO certified) in California to guarantee 99% purity with zero heavy metals and endotoxins.

Intended Use

This material is sold strictly for the purpose of laboratory research, including but not limited to:

• Cell Signaling Studies: Investigating the interaction between peptides and growth factor pathways (e.g., VEGF, FAK).

• Tissue Culture: Analyzing cellular migration and proliferation in non-clinical models.

• Stability Testing: Assessing peptide degradation rates under various pH and thermal conditions.

Restriction: This product is not a drug, food, or dietary supplement. It has not been approved by the US Food and Drug Administration (FDA) for any clinical application.

Storage & Handling

• Lyophilized State: Store at -20°C (-4°F) or below. Keep vial specifically protected from light to maintain peptide integrity.

• Reconstitution: For best results, reconstitute using Bacteriostatic Water or Sterile Water for Injection (USP) strictly for solution preparation.

• After Reconstitution: The solution should be used immediately for research purposes. If storage is required, maintain at 4°C (39°F) and use within a standard research timeframe (typically 1-2 weeks). Avoid repeated freeze-thaw cycles.
