LL-37 5 mg

LL-37 is a naturally occurring human cathelicidin peptide produced by immune and epithelial cells as part of the body’s innate defense system. It plays a key role in host defense, microbial regulation, inflammation control, and tissue repair. Synthetic LL-37 is widely used in research exploring antimicrobial activity, wound healing, immune modulation, biofilm disruption, and cellular regeneration. Its unique ability to interact with pathogens while influencing immune-cell signaling makes it a valuable tool in immunology, dermatology, and regenerative-biology studies.

Key Benefits

(Observed in controlled preclinical and research environments)

  • Broad-Spectrum Antimicrobial Activity: Supports studies involving bacterial, viral, and fungal defense mechanisms.
  • Immune Modulation: Helps examine cytokine regulation, innate immunity activation, and inflammatory signaling.
  • Wound Healing & Regeneration: Frequently used in research on epithelial repair, angiogenesis, and tissue restoration.
  • Biofilm Disruption: Useful for studies evaluating peptide interaction with microbial biofilms and surface pathogens.
  • Dermatological & Barrier Function Models: Studied in skin-healing, barrier integrity, and inflammatory skin-condition models.
  • Synergistic Potential: Often combined with other peptides or growth factors in regenerative and antibacterial research.

Potential Side Effects

(Typically mild and dose-dependent in laboratory studies)

  • Temporary skin or tissue irritation at administration sites
  • Mild localized redness
  • Occasional warmth or tingling
  • Rare instances of transient inflammation in high-concentration models

Responses vary based on experimental conditions, biological model, and peptide concentration.

Storage & Stability

  • Store lyophilized LL-37 at 2–8°C for short-term use.
  • For long-term preservation, maintain at –20°C, protected from moisture and light.
  • After reconstitution, store at 2–8°C and use within the recommended stability timeline.
