LL-37 Nasal Spray 5mg — 10 mL

Description LL-37 is a human cathelicidin-derived antimicrobial peptide. It is studied for its broad-spectrum activity against bacteria, viruses, and fungi, as well as its roles in immune modulation, wound repair, and inflammation balance.  Product Highlights Each vial contains 10 mL solution (~100 sprays) Each spray delivers 0.1 mL = 100 mcg LL-37 Total LL-37 Content: 10 mg per vial Specialized pharmaceutical-grade nasal solution — designed for comfort and ease on the nose Unlike many other nasal sprays, this formula avoids irritation and dryness Packaged in Class A, lead-free pharmaceutical glass bottles Tamper/Child-Proof Cap Orifice Reducer for integrity, sterility, and ease of use Description LL-37 is investigated for antimicrobial defense, immune regulation, wound healing, and inflammation control. It has been studied for roles in epithelial protection across skin, lung, and gastrointestinal systems. Benefits Broad-spectrum defense — studied for antimicrobial activity against bacteria, viruses, and fungi Immune modulation — explored for balancing innate and adaptive immune responses Wound healing — linked to angiogenesis and tissue regeneration research Anti-inflammatory — studied for calming excessive inflammatory signaling Barrier protection — interest in skin, lung, and gut epithelial defense Localized Effects with Nasal Spray Rapid uptake through the nasal mucosa Direct antimicrobial and immune-modulating effects in respiratory and systemic pathways Formulated with a specialized isotonic nasal vehicle to minimize irritation and dryness What Researchers Use It For Mechanism: cationic peptide disrupting microbial membranes and signaling immune pathways Role in epithelial defense of skin, lung, and gastrointestinal tract Angiogenesis and wound-healing effects in tissue models Exploration in sepsis, chronic infections, and autoimmune conditions Identity & Specs Sequence: LLGDFFRKSKEKIGKEFKRIVQRIKDFLRNLVPRTES Formula / M.W.: C215H358N64O46, ~4493 g/mol CAS: 221231-10-3 Form: Sterile nasal spray solution Net per vial: 10 mL (~100 sprays) Total Content: 10 mg LL-37 per vial Purity: ≥99% (HPLC) Identity: MS-verified (per COA) Storage: Refrigerate 2–8 °C, protect from light Selected Research PubChem entry — chemical identity: https://pubchem.ncbi.nlm.nih.gov/compound/16130166 Antimicrobial and immune roles of LL-37: https://pubmed.ncbi.nlm.nih.gov/12794199/ LL-37 in wound healing and angiogenesis: https://pubmed.ncbi.nlm.nih.gov/16489025/ Role in lung and epithelial defense: https://pubmed.ncbi.nlm.nih.gov/17923416/ LL-37 immune modulation overview: https://pubmed.ncbi.nlm.nih.gov/20193060/ ⚠️ Disclaimer This product is intended for laboratory research use only.
