How LL-37 (5 mg) Supports Research
LL-37 (5 mg) is primarily used in research to study how the immune system works and how peptides interact with cell membranes. It helps researchers explore how antimicrobial peptides influence cell permeability, immune cell activity, and the release of immune signaling molecules under controlled conditions.
LL-37 is also studied for its role in immune regulation, particularly its interactions with cell receptors and its effects on inflammation. It is used in in vitro research on cell barrier integrity and immune cell communication. These studies are conducted in laboratory settings and focus on gaining a better understanding of immune responses.
Research Applications & Usage Information
LL-37 (5 mg) is commonly used in research for:
- Used to study host-defense peptide mechanisms in vitro/in model systems
- Analyzing immune signaling and inflammation pathways
- Research on Toll-like receptor (TLR) and innate immune system function
- Investigating the integrity of cell barriers and mucosal defense
- Exploring interactions between peptides and cell membranes
- Research on tissue responses in controlled lab models
These applications are for investigational purposes only and are conducted in laboratory settings.
Handling and Storage Recommendations
- Store at 2–8 °C (≤ –20 °C long-term)
